Well yeah: more cops means more arrests, which means more prisoners, which means more slave labor.
Remember the 13th Amendment:
Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.
No sarcasm tag necessary; that's what conservatives genuinely want.
If the US wasn't spending more on its military, than the next 5 nations combined, it would be considered a terror state that belongs to the axis of evil and would be sanctioned into oblivion.
