Re: American Cops need reforms Re videoing cops
It is _not_ illegal. It's legal in every state.
Every so often, state politicians try to create laws that make it illegal, but those laws get challenged and struck down as unconstitutional.
In some states audio recording is illegal without consent of all parties, but most require only the consent of one party.
What you _can't_ do is interfere with the police doing their work so people filming may have to make sure their recording shows that they maintained a reasonable distance.
