The government is required to respect privacy, not to be stupid. An area's status as a crime hotspot can reasonably cast suspicion on those visiting it late at night.

I also think that laws designed to be broken so that you can throw false "should have follow law" excuses once cops selectively enforce it are lowering respect to law enforcement.
There's absolutely no requirement to 'respect privacy.'
