There’s been a misconception in the media lately about it being illegal to videotape cops in three states; Maryland, Massachusetts and Illinois.
In Massachusetts, it is illegal to secretly record anybody without their consent, but there is no law against openly videotaping anybody in public with or without their consent, including cops. In fact, charges have been dropped against people who have been arrested for videotaping cops in public in Massachusetts.
In Maryland, state police and a certain prosecutor treat it as if it is illegal but another state attorney as well as the attorney general disagree that it is illegal to videotape cops in public. The debate should be settled entirely by the time Anthony Graber goes to trial on October 12. Also, the ACLU, which is backing Graber in this case, is asking the law to be further clarified.
