I actually lol'd at this.
In a perfect world, yes. But I ask you, whos definition of reasonable? Was the judge there that night in the alleyway? Did the cops see the situation, feel the anxiety and danger you did? Cops have pepper spray, tasers, batons (and backup) to protect them, youll find what they think is reasonable might just differ from yours.
Im sorry but I completely disagree with the bold part of your sentence. Ive seen people go down for some incredibly unreasonable reasons. Maybe where you live but over here your expected to just lay down and get the **** kicked out of you. No thanks.
Once again, who determines when its reasonable to kick someone where? Its all very well to comment when your sitting back observing, or reading about it, but what about being there in the moment and fearing for your life? What if an assailant is trying to kill me, and I dont want him getting back up, he might be armed or just way bigger than me, or perhaps on drugs etc. I see what your saying, and I agree people use dubious amounts of force sometimes, but should I be punished for reacting too violently when someone else provoked the situation in the first place? Is the onus on me to show restraint and carefully cuddle an assailant into submission when he couldnt give a **** about me or my safety? Plenty of guys round my neighborhood who wouldnt give a second though to stomping on my head while im down, yet im expected to not use the same force in response?
In a perfect situation I would use only the exact amount of force required to stop an attack...but the reality is I am not going to go gently on a criminal just for his sake, someone my size cant afford to crank on a strength based arm lock and simply subdue a 6'6" drunken rugby player. Im going to punch him in the throat, consequences be damned, I read the papers and I know people get stomped to death in my city, that aint gunna be me...I got a wife to come home to.
