USadly the laws making it illegal to photograph police, still exist in the EU. the one here in Spain dates from the Franco dictatorship, and is quite similar to those used in most North African countries. This will soon change, because enough of such tapes and photos, escape the police, and have turned around enough cases of police misconduct, that when challenged judges are tending not to enforce the law. I have a personal solution as I take a lot of video clips. If my clip is controversial, or likely to be confiscated, I substitute the chip for a clean one, and put the evidence in my shoe.
