Decent airport in terms of architecture, planning, etc. However, every time I encounter TSA at this airport, I have extra screening for no reason whatsoever. They told me once i was "randomly selected" for a full pat down. My partner also had his pockets checked without being informed beforehand that they were going to touch him. It seems like if the police are not allowed to have such a position of power, how on earth does TSA?

If you are checking for something in particular, because it is the Silicon Valley or something, please inform those in line about what you are intending to do. At least try to be amicable towards passengers...
