Consider a scenario involving a full-blown surveillance: email monitoring, cellphone monitoring, online activity monitoring, credit card monitoring, bank account monitoring, and also, 24x7, door-step, snitching-neighbors.
Also consider that the target of this surveillance is a vanilla, boring, life-long law-abiding citizen, with no criminal-record whatsoever.
How high is the bar to allow for such surveillance to target such individual? Is it lawful? Is it abuse of power?
