We took and break and Jen and Amy decided to go around the corner to go to my parents grocery store and get some drinks for us. Mean while the guys and I went outside to check out my car. As I'm showing off and revving my engine I hear Jen run towards me and shout "BABE some guys were trying to beat up your father GET THEM"!!!!
Naturally, I saw red

I look up the street and see Jeremy and Angel running into the back of a house, I follow and hear Jeremy say they're on the roof of the garage.
I sneaked along the side of the garage and peeked around the corner to see four sets of legs dangling from the roof, I ducked back behind the wall and let the guys know where they were. I slowly got underneath the guys legs and I grabbed two sets and stuck their feet underneath my armpits and dropped to my knees and dragged one guy off the roof. As he fell his face came down on the fence that was next to the garage. He tried to turn and swing so, I stepped behind him and put a knee to his back, I grabbed him from the back and took him to the ground. I yelled and commanded him to stay put but, he would not listen to words. As I got up he tried to get up and swing again so, I quickly let my hand do the rest of my talking with one good knock. He still tried to get up so my knee met up with his face and he at once went face down knowing that I was not playing games with him. Angel and I escorted him to my parents store and had him locked inside till the police came. I took off again looking for the others but couldn't locate them. An officer and I started to search again on foot after i gave a thorough description of the others. the officer and I started looking at the space behind a dumpster and saw no one. We walked away from the area but, something told me to look again in the crack beside the wall and the dumpsters and I saw the second individual! As I yelled to the cop the thief took off behind the dumpster and the apartments. I and the officer gave chase and cornered the idiot on top of a fenced in wall. I yelled "Get the FUCK OVER THE WALL" and he says "hey can we just talk about this man come on" and I said " you can talk to the cops". As I say that the officer comes up next to me and sees the individual and commands him to come over the fence the thief says he can't make it and he's going to take another way around. This made the cop put his Glock in the assholes face and magically the idiot can get over the fence. As soon as he step foot on our side both the cop and I put our weight on the ass and slammed the punk to the ground. I put the guys face looking at the ground and put my right knee on the back of his neck and locked his right arm and his left wrist in a joint lock and the officer cuffed him and we stood his ass up and put him into the back of the car.
So, after all of this I go back to the store and the first punk is still in the store but, now in cuffs with five officers in the store around him and about 13-15 squad cars out front (oh by the way my parents are really good friends with the cities dispatchers and many of the high ranking officers). The idiot still runs his mouth and says to me, in front of the cops, "Oh these your parents, Okay, now I know where you live, I got something for you, this ain't over, you gona get yours"! Before I could even say, "Mother Fuc..." An officer stepped in front of me and said, "what the hell you just say??? Did you just threaten him? Ok asshole now your going to jail for that too"!
After we talked to the officers at the scene and talking to my parents. The four guys apparently tried to pawn off a fake twenty to my mom and my mom said that it was a fake and that she couldn't accept the bill but, the guys started to lie and say that they gave my mom a dollar bill not a twenty and that my parents were trying to rob them. After getting loud and cursing at my parents and refusing to leave the store my mom said that she was going to call the cops and told my dad to go out from the bullet proof glass and lock the front door. And that's when the guys tried to jump my dad.
So I got two of the guys and the other two guys are still not in custody I believe but, the guys are all related and they live in the apartments across the street from my parents and I so, I or the cops will catch the rest of them. I know exactly what they look like.

I just got a few scrapes and bruises but, nobody besides the 4 guys were hurt.
My question is what would you have done in this situation? Do you think I went too far? Was I over stepping my boundaries as a citizen?
