You are the only one who has brought up the issue of drugs. I see this savage behavior as the result of the illegal drug culture poisoning the minds of everyone it contacts. I believe these illegal drugs are affecting the logic centers of the brain that controls social behavior. The violence and savagery are the collateral damage of the industry that sells euphoria at the expense of the human body. For a look into the effects of cocaine go here.

I had a close up look at what they do working the cab.
Could tell too many stories, some probably wouldn’t be believed.
Those pics at the site are of a SEVERELY damage brain. I wonder how long the user had been using.
I sustained a brain injury about 10 years ago, pretty bad but recovered mostly over the past decade.
At my WORST, my MRIs never showed the damage at the site you sent me.
Wow.
