Like "checkpoints" for weapons searches.
Lived in Brasil (a republican democracy) for two years in the 1980s. A "checkpoint" every 25 to 100 kilometers on the major highways.
Mixed emotions. Felt powerless with regard to civil rights; felt comfort for the increased security.
I was stopped at a roadblock the other day, four policemen, stopping all traffic both ways, "TO SEE IF I WAS WEARING MY SEATBELT". I had to produce a drivers licence, have my plates checked and they checked inside the backseat. They said it was for my own protection. This was from civil police, looking out for me, bless em. From little seeds a big tree grows.
