Legally? Yes. In practice? You will probably get a free tour of the American legal system, from handcuffs to squad car, cell, lawyer, courtroom.

It’s actually possible you’ll also get to experience “civil rights violation and settlement” tour enhancements.

This question is from 2015.

You can film them, just not obstruct with them executing their official duties.

Personally, I'd wait another 3 years to visit until this brainless ass clown is out of office (or maybe 10 years later after our society recovers a bit from completely melting down because we have a civil war when said ass clown refuses to peacefully leave office and the large number of ass clown citizens back him up because they are afraid to truly live freely)

I make this recommendation as a very reluctant republican (who proudly has never voted for president ass clown).
