5 minutes late to the scene of a murder, wondering what I would have done

So a rising post on both the Orlando subreddit and the news subreddit is regarding a man who shot and killed a burger king employee. I live right around the corner, and was at the scene less than 5 minutes after the 911 call came in.Part of me wonders what I'd have done but another part is concerned about whether or not I'd have been able to do anything anyway.The victim was 22, and on the job less than a week, and was beaten, headlocked, then shot and killed because of a backed up drive thru. Had I witnessed it in its entirety I want to think I'd intervene but I also cannot help but think that I'd be far to interested in self preservation and would just try to leave, like most will say I should.I know we should never insert ourselves in situations or try to be the law/vigilante but knowing the facts now I wish I could have done something to prevent this young kid from being murdered less than a week into his first job.I'm pretty fucked up about this and I've been talking to my fiancee about it at length after reading the article and realizing why 8 deputies were in the parking lot as I left with our Wendy's. Had I left home sooner, instead of taking the dog out, and/or had we chose whoppers over 4 for $4s, I can't help but feel I would have been involved in one way or another.I talked to my fiancee about whether or not I should post anything because I don't want to come off as "oh I would've been the hero" or "I would have saved that guy" but I can't help but feel like I would have done something, knowing what I do now.Anyway, I'm really just looking for some insight on whether or not you guys and gals have ever felt like this or even witnessed a situation that you felt you could have done something or did do something. via /r/CCW https://ift.tt/3frlBMy
