A Des Moines police officer is recovering after being seriously injured when he was struck by a colleague's bullet during an apparent shootout with a suspect Tuesday morning.糖心vlog reached out to several law enforcement experts to learn what the officers involved in Tuesday's shooting may be going through and how the community can help support them.We also spoke with a former Polk County prosecutor who has expertise with domestic violence cases and the dangers officers face when responding to these calls. Former DMPD police chief reacts to shootingFormer Des Moines Police Chief William Moulder said Tuesday morning's shooting is a "tragic event."Moulder served as chief of the department for 18 years, from 1984 to 2003. He said during his time there, something like this never happened. He said an officer being shot by another officer is rare."Those are such chaotic situations, and you get tunnel vision," Moulder said. "You only see the bad guy and you really are not cognizant of much else."He said officers spend more time on firearms training than anything else. Moulder said mental health will be important following the shooting."The officer that did the shooting and hit the second officer is going to be really remorseful about it," the former chief said.Iowa DCI special agent says it will 'be awhile' before more details are releasedThe Iowa Division of Criminal Investigation is investigating the early Tuesday morning shooting that left one suspect dead and another officer seriously injured. According to police, the officer was wounded by friendly fire.Special agent Adam DeCamp said the Iowa DCI is currently working on gathering facts and evidence. He said they're looking at bodycam footage, speaking with witnesses and looking at the weapons used."One of the officers was injured and we haven't had an opportunity to talk with them," DeCamp said. "It's going to be a while before we can really release a lot of new information about this shooting."DeCamp said it's not required the DCI investigate cases like this. He said the Des Moines Police requested the investigation."I believe that speaks to the transparency that the Des Moines Police Department is trying to provide in this situation," he said.The Polk County Attorney's Office and the Iowa Attorney General's Office will be involved in the case. DeCamp said they can make a determination on whether the officer acted within the scope of the law of Iowa pertaining to police officers.Former DMPD officer offers perspectiveTuesday morning's shooting instilled an array of emotions for Iowans, especially current and former members of law enforcement. Dave Murillo is a former Des Moines Police sergeant who served in the department for years. He retired in 2013. He says Tuesday morning, just like any morning something distressing happened to a member of law enforcement, is a terrifying feeling. "Your heart just goes up into your throat anytime you hear a police officer has been shot," said Murillo. "Your first reaction is 'Oh my God' and then you hope the officers are OK."Murillo tells 糖心vlog situations like Tuesday morning are high-stress, high-emotion, and adrenaline-charged moments. During those kinds of moments, the former sergeant says there are times members of law enforcement can't control what they're sent there to control. "I was one of the first officers on scene of the Drake Diner homicides. There's officers converging onto that diner from all different directions," recalled Murillo. "We're all coming in from different directions. What if that suspect—what if we could've caught him in the parking lot and gunfire would have happened? Crossfire. Those situations happen." Murillo tells 糖心vlog, what helps following situations like this is letting members of law enforcement know they're supported and loved by the community they serve. "They have a very dangerous—sometimes thankless—job to do," said Murillo. "When these sorts of things happen, the best thing the public can do is get on Facebook--Des Moines Police have a Facebook page—and let them officers know how much you appreciate what they do." Experts emphasize the dangers of domestic callsThe incident Tuesday highlighted a risk experts in law enforcement and domestic disputes said is an ever-present danger.Iowa Law Enforcement Academy Director Brady Carney said responding on calls relating to domestic disturbances are some of the most dangerous an officer may face. The potential for violence is often difficult to gauge without context to the situation."Domestic incidents involve a variety of factors that law enforcement has to take into account, and many times they don't know those factors until their arrival," Carney said. "A lot of times (during domestic call responses), there's emotion, there's trauma, there's a relationship that's been established that's involved in family dynamics. So, when you when you add those factors to these calls for service, that just adds to the level of uncertainty, and many times danger, that law enforcement has to deal with in their response."However, Carney said preparing officers in training to handle the complexities of a domestic call can be difficult."All of those things are not easily replicated in the training world, those are a case-by-case scenario that officers have to evaluate and take in so many different factors to process and work through every call for service," he said. "We try to cover as many of those as we can in training environments, but it's so hard to replicate real life."While most calls do not result in gunfire, Carney said uncertainty leaves the potential for officers to be injured. "When we train law enforcement officers, we tell them that this is the most dangerous call that they will be dispatched to," Iowa Assistant Attorney General Shannon Archer said of domestic disturbance calls. To experts in the field, like Archer, a former Polk County domestic abuse prosecutor, the result is sad to see -- but not surprising."Once an offender or someone who is a domestic abuser loses that control, it can be even dangerous, not only for their victim but for others who are around in that situation," she said.
