I recently posted that recording police in PA is a crime and referenced the statute.
Eric Peters of www.epautos.com emailed and said he feels these laws were put in place for the protection of citizens and all arrests pertaining this issue (in and beyond PA) have been dismissed. Well maybe so but I feel we are still taking a chance. Never-the-less Austin White lists 9 positive things here that happen when we create a visual record of what the boys in blue do.
Gary North thinks video is a good idea also.
