I have seen street photography done without being invasive. A lot of strangers on the street will even happily pose in weird ways if you ask them. And many will give the okay AFTER you have taken the photo, if you just introduce yourself and ask.
The worst is the people who photograph poor or homeless people - trying to capitalize off of someone else's misfortune, but claiming in their vanity that they just want to bring "awareness." They are rude, vain, and liars.
It is legal. But it is also legal for me to stand outside your house every morning and follow you to work.
Except in UK. Such behaviour could result in arrest and an appearance in court under S5 of the Public Order Act of 1986 for causing Alarm, Harassment or Distress, or if speech were also involved then the Harassment Act of 1996 could be invoked with a much heavier penalty.
