> While it is good that the UK version doesn't send you to pretrial jail, you still have to fight the charge

The UK has much stronger protections at the start of this process though. Pre-charge detention is capped at 96 hours, charging decisions are by a professional, non-political, and non-elected governmental department who have accountability, political cases require sign-off right up the ladder, and bail is presumed in favour of release. You might get a police visit, worst case scenario an arrest and your devices seized, but it's also a case that will go nowhere because the CPS won't charge it. And you don't really get this whole "rogue sheriff" issue in the first-place, because we're not insane enough to politicize local law-enforcement.
