The most paranoid mutherfuckers in the world. You can't be a teenager at 6 pm and walk five steps before they're on you asking where you "got your drugs". They shine a flashlight in your face and threaten to take you in because you're looking "spaced out".
The London Police are ridiculous. I was walking down my road at 8 o'clock and they stopped me, saying I looked like I was on heroin! (true story)
