In public there is no expectation of privacy so no permission needed in any state. There have been a few questions like this in various threads in the past including one where a screener claimed it was illegal to photograph/video them at work and were informed they were wrong they had no expectation of privacy and could quit if the didn't like it, but it was not illegal.
