Not a good approach at all. The law must mean what the law says, otherwise there is no law at all, only unrestrained power. The Anglo-American conception of law is that it is to be a restriction on power. Your approach is to throw away the whole legal structure since Magna Carta and to fall in with Hobbesian anarchy.
I wish the DOJ were taken out of the control of the white house altogether. In Michigan we’ve got an elected AG and it works very well with him operating outside the control (and sometimes in conflict with) the governor.
