The right to remain silent, the statute of limitations, and the presumption of innocence should be revoked or at least limited for government agents when acting in their official capacity. Fir exampke, when police or ATF turn off their bodycams, and then a suspect is shot and killed, or they were on but the footage is then deleted, there is no reason to presume innocence on the part of the agents. Similarly when the FBI releases footage of the Jan 6 breach, but the frames just happen to glitch when the barricades are first breached. The odds against that happening by pure chance are astronomically high and should be admissible to establish malfeasance.
Turning off a bodycam or deleting video footage in order to hide a non-justified shooting, assault, thievery, etc. are NOT official job duties, thus meaning that it is a personal act, the officer’s own personal azz is on the line, and as a result, they have 5A protections. Govt. agencies’ and employees’ official acts do not have 5A protections. Ike did an EO that said if an exec branch govt employee invokes the 5th while testifying as to an official act, they shall be fired immediately. That EO is still in force today but FJB’s minions do not enforce it (they’re so smart (/s) they probably don’t even know it exists or that it has never been countermanded by further EO’s.)
