To preserve (themselves) and protect (themselves)
What apparently passes for good police work in Ohio (and undoubtedly elsewhere):
Police aggressively questioned the tearful girlfriend of a young black man they had just shot dead as he held a BB gun in an Ohio supermarket – accusing her of lying, threatening her with jail, and suggesting that she was high on drugs.
Tasha Thomas was reduced to swearing on the lives of her relatives that John Crawford III had not been carrying a firearm when they entered the Walmart in Beavercreek, near Dayton, to buy crackers, marshmallows and chocolate bars on the evening of 5 August.
“You lie to me and you might be on your way to jail,” detective Rodney Curd told Thomas, as she wept and repeatedly offered to take a lie-detector test. After more than an hour and a half of questioning and
statement-taking, Curd finally told Thomas that Crawford, 22, had died.
But it’s people wearing t-shirts that are the real problem.
