Today I noticed that police people on horses are utterly ridiculous. I just don't understand how having a police man on a horse is useful in central London? If anything, surely the horse is a hindrance to catching a burglar or really doing anything quickly in a crowd? Unless the primary objective is to be the most noticeable person on the street I can't see any reason why you'd find it helpful to have the added distraction of keeping a horse under control whilst doing your job.
So, those are basically two things. One brilliant. One rubbish. Enjoy.
