What the police can ask for legally and what they ask for based on a credible threat are rather different.
If 99.99% of the people comply and .001% of the people refuse and the cop involved slugs the non-complying person, giving them a life changing injure. and even if that cop "doesn't get away with it" - gets filmed, get drummed out of the force and the city pays a million dollar settlement, the cops, collectively, will still get away with it and keep doing it since it nearly always works. And the one cop being caught is extremely optimistic.
Even with suspicion, it's unlikely that they can forcefully demand social media information.
How can a cop request information in fashion that isn't forceful? The softest, most polite question is backed by the threat of both violence and arrest.
