Individuals have a right to record police activities

"The Justice Department is urging a court to affirm individuals' rights to record police under the First Amendment, filing a statement of interest in support of a journalist suing over his arrest while photographing Maryland officers.

"In the statement filed this week in a federal court in Maryland, the Justice Department argues that not only do individuals have a First Amendment right to record officers publicly doing their duties, they also have Fourth and 14th Amendment rights protecting them from having those recordings seized without a warrant or due process."
