Police Surrounded And Pulled Guns On Me While Walking With My Family.

In short: My wife and I were visiting my daughter and boyfriend (both students at Purdue University). We took them out for dinner and a couple games of pool. Afterwards we were walking them back to their apartment when all of a sudden I see two police officers with guns drawn (took me a second to process what I was seeing) and I hear someone say something to the affect of “the one with the hat” (I was wearing a hat). Next thing I know I’m surrounded by about 7-9 cops with their side arms pointed at me telling me to put my hands up. I totally complied. They also told my wife, daughter, and her bf to step forwards (clearly I was the suspect). A police officer tells to put my hands behind my back and asks if I have a firearm on me? I comply and say i don’t have a firearm on me and he quickly checks my waistband and pocket. Recall him asking if I have ID on me at this point and say yes it is in my pocket and ask if he wants to grab it if or I should. Pretty quickly he says “that isn’t necessary” and tells me “someone called in about a husband pulling a gun on his wife” who fit my description (green hat and shirt). At that point the realization of what occurred hit me and I must have been feeling all the adrenaline releasing because I remember I started shaking. One of the police officers asked, “are you ok?” Honestly, I’ve always been pretty pro-police but the adrenaline dump had me redlined and I responded something to the effect of, ”fuck no. I’m not fucking ok. I fucking hot. You fucking drew on me in front of my wife and children” (meaning daughter and her bf). Wife ended up calling me over and saying “let’s go” (thank God she did) and we walked away.
Needless to say I slept like shit last night and every time I think about it, including now, I’m still feeling like I’m getting “ramped up.” My wife is tough as nails but my poor daughter and her bf, I feel terrible for. Basically I feel like I did something wrong.

I’m pretty certain there’s zero legal course of action to take. However, it would have been nice for the guy who looked (based on age) to be the sergeant to have offered an apology to my family and I.
Needless to say my head will be a bit fucked up knowing I was one pull away (I’m a gun owner and 22 yr retired Army dude so plenty of firearm experience) away from being turned inside out. More importantly, my daughter seeing that shit. Law enforcement needs to do better. There was an appropriate escalation of force process that I feel was not followed. Anyways, thanks for letting me vet. Feedback appreciated.
