"They can't remove it without knowing who the warrant is for" is absolutely Flocks problem.

They're alerting on a license plate but yet somehow they can't turn off that license plate alert using just the license plate number? Fucking bullshit

Wouldn't it be the purview of the cops to update Flock that the plate is no longer of interest and to stop alerting on it? I'm no fan of Flock, but let's put the onus where it is deserved.
