Why would they need permits?
Can this be done? Sue the idiots who wrote the article and the newspaper for “endangerment” to the police officers.
Contrary to what those who believe the police only shoot dogs do, the policemen’s jobs are stressful enough without adding to it.
Although the police automatically "have permits" for their duty weapons, I believe most (if not all) cops also have personally owned firearms that they keep at home for the defense of their families and themselves in "off-duty" hours. Of course, the requirement for "permits" varies widely by geography.
