That is not true. State laws cannot interfere with the work of federal law enforcement, but can require certain behaviours.

Eg. States set speed limits. A federal LEO can break these when required for their duties (eg. chasing a suspect), but only when required (eg. if they are late for a meeting, they still have to obey traffic laws).

Body cameras do not seem to directly interfere with an LEO’s duty, unless “avoiding accountability” is literally their duty.
