I share your discomfort. Attorneys General like Janet Reno and Eric Holder are too fresh in my mind. I've never been a cop hater, but having seen them stand with their thumbs up...while Trump supporters and conservatives get pummeled by rabid dog leftists have left me with a sense that they know what side their bread's buttered on. It answered my long held question about where I stand with them.
It may be too soon, at best, for Donald to reverse this. Let war be war. Let policing be policing. Call on the appropriate agents to carry each out.
