I think the recent problems that law enforcement has been having lately were brought on by themselves. Too quick to shoot, empty their clip in some unarmed victim and ask questions later, or sweep all questions under the rug.
I'll stick with respecting our troops the way I always have, and thanking them for their service. A police officer is doing his job and paid a wage for it, like firemen, construction workers, or anyone else.
Our military are many times place in areas where we have no business being, and they lose their lives or return mentally or physically crippled to their own country, only to be ignored, rejected and many times if they don't commit suicide, are left homeless to fend for themselves as thanks. Those are the fine Americans who should be shown gratitude.
