This is all very interesting... So, it's a pretty common effect, here on BL..
Anyone ever heard of "Disinhibition"? Basically, it's when something or other (a drug, in this case) causes the person's normal anger-inhibition (that biochemical thing that stops most of us from acting out our insane, angry thoughts on others when we're even slightly upset) to be suppressed. Benzos are renowned Disinhibitors of this type. I've personally gone absolutely fucking crazy while on medium doses of Ativan, Xanax, or even Klonopin - the effects would get crazier when mixed with opiates..
Got myself and my band banned from the city of Santa Monica, thanks to my inciting a destructive 4-person riot (the band, that is heh) that pissed the locals off. That night it was Klonopin and Oxy. I don't blame them, though - we grabbed handsaws and other tools and began dismantling parts of the club we'd just played at hahaha Cops came, cuffed us, told us never to come back to their "town". Hilarious!
Also, during one insane night on Ativan+Norco, some self-righteous, stuck up weed dealer refused to come downstairs to his neighbors pad (his neighbor=my friend) to sell us some weed. It was a trip down a few stairs, not stairwells. So after my friend talked shit to his lazy ass on the phone, he came downstairs, with a knife, opened the door and stepped in - I was quite pissed about his retarded behavior, and totally "Disinhibited" so before he even said a word, I stood up from the couch and ran at him, tackled him, took the knife by twisting his wrist, then held him in a rear naked choke for a min, while yelling weird shit that just...came to mind hahaha
Ahhh Benzopiate Nights.... glad I remember them.
