After hearing account after account from friends and acquaintances of rude and sometimes abusive behavior by federal officials in Immigrations, TSA, and others, I spoke by telephone to a fellow at TSA in Washington. He was agreeable and helpful, which is not a response one always gets in the capital. Anyway, I subseqquently wrote him a letter, reproduced below, which addresses matters that in the past have been of interest to readers.
