So these criminals that have been performing the illegal searches. The next step is they'll be charged with false imprisonment, extortion, and conspiracy, right?
Oh, okay then, how about at least for deprivation of civil rights under the color of law?
Well then, what about monetary damages for the people whose data was copied, devices were stolen or could no longer be trusted, wasted time and missed flights, costs of retaining an attorney to defend themselves, etc?
Oh, the result is that the criminals that did this are just going to have to pause for a little bit until some attorney working for their agency, whom we are also paying for, writes a new justification with slightly tweaked reasoning, at which time the perps will resume?!?
Sovereign immunity strikes again. None of these terrible authoritarian dynamics are ever going to be reigned in until sovereign immunity is severely curtailed. At the very least we need civil liability that compensates the victims out of the department's budget. Ideally there should be criminal liability, either on the individuals performing the illegal actions, or if they're following written policy then whomever instituted that policy.
And if you think this sounds extreme, then note it's still more lenient than what the rest of us get! Security guards, private investigators, and even just individuals defending themselves still manage to operate while staying well away from the edges of the law. And in general, staying away from the edges of the law is the exact dynamic we want for those involved in physically coercing others.
