Basically, if you are in a public place you have no right to privacy- yes anyone can take your picture.
They can also publish that picture for "artistic" purposes- no they can not use it commercially without a release.
I used to do a lot of street photography- not so much anymore. Everyone is paranoid.
But again, he had every right to take your picture if you were in a public area without any expectation of privacy. You of coarse also had the right to take his picture.
Public places like bathrooms are different- there is an enforceable expectation of privacy there.
