Your Rights as a Photographer in the US
When in public spaces where you are lawfully present you have the right to photograph anything that is in plain view
When you are on private property, the property owner may set rules about the taking of photographs
Police officers may not generally confiscate or demand to view your photographs or video without a warrant
Police may not delete your photographs or video under any circumstances
Police officers may legitimately order citizens to cease activities that are truly interfering with legitimate law enforcement operations
Note that the right to photograph does not give you a right to break any other laws
