If a government agent breaks into a dwelling at 123 E. Fifth Street, without a warrant authorizing him to do break into 123 E. Fifth Street, and in the absence of obvious exigent circumstances that would justify such a break-in, why should he not be regarded and prosecuted as a robber? Even if he has in his possession a warrant for 125 E. Fifth Street or 123 E. Sixth Street, such a warrant in no way authorizes him to enter 123 E. Fifth Street.
I've never heard of a cop being prosecuted as a robber under such circumstances, but I see no reason one shouldn't be.
No intent to rob and no actually robbery. Breaking and entering, and if they so much as touch an occupant then felonious assault are possible charges. Then at the civil trial, mental anguish.
