Ok so some of you may not like this. Can you film at a walmart? Yes can you film a police station? Yes but if you do it more then once it is suspicious! It is the duties of the LEO to investigate a person that may be suspicious of something to try to find out what their intent is. It is legal for a LEO to detain you as long as needed to determine if you are not a threat to your self or the public. If the man would have given a reasonable reason for the filming then there probably would have been no issues. Is actions raised a red flag. There is also the fact that we don't know the history of this man and the LEO. Now!! The LEO was NOT acting professional at all! !!!! The personal stabs to the man were wrong. a LEO'S first goal is to maintain a professional attitude, unfortunately he didn't. This type of stuff is happening more and more these days! people need to understand that if you are going walk down the street with an AR-15 on your back, or film a police station, or not roll your window down more then an inch at a check point, you are going to throw up lots of red flags and cause a lot of questions from a LEO! also little FYI (GS 14-223) resist, obstruct, delay LEO can arrest you if you delay him from doing his duties i.e not answering questions, answering questions with questions........
