Is Edinburgh safe in England?

It gives people the impression that the big city with good public security in Britain is London, Edinburgh is ok, and the tourist city is better as a whole, but Edinburgh is obviously not as good as London, with many street vagrants and poor sanitary environment. Sometimes at seven or eight o'clock in the evening, the tramps on the Wave Bridge still gather there, but life should not be much problem at ordinary times. Personally, what I don't like most is Manchester City, the old city, where there are many vagrants and beggars, and I have met several swindlers in the street. Generally speaking, Britain is better than other European cities.
