It would interesting to hear of other folk's experiences regarding any threats, intimidation, abuse and theft they have experienced when shooting 'Street'.
Thankfully, despite shooting over many years, in many countries, cultures and environments, my negative experiences have been few and far between. I've occasionally experienced unhealthy interest in my cameras which I've managed to deflect. I've been followed by gangs in Jodhpur, India, but by calling them out and confronting them they disappeared into the crowds as fast as they had appeared.
I'm naturally attracted to those areas generally considered to be off limits, poorer ghettos, red-light districts and known drug dealer areas. Somewhat surprisingly perhaps, but the safest places I've ever been with camera in hand have been the cities in Morocco, a society where even the mere presence of a camera can cause apoplexy. The people have been friendly, welcoming and helpful.
I know, famous last words!

Would love to hear your own experiences but given the amount of active contributors here I'm not holding my breath.
