What you’re asking is that the actual be sacrificed to the hypothetical, i.e., that the actual rights of law-abiding citizens not to be terrorized by outlaw DEA agents, be sacrificed on the ground that widespread terrorization of this kind may have snagged (apparent) bad guys such as Treyvon Martin.
That idea isn’t compatible with a free America.
