RadirD, In 2007, over a year before Obama assumed office, 57 cops were feloniously killed in the line of duty, and 59,000 were assaulted. In 2012, 48 law enforcement officers were feloniously killed in the line of duty, and over 52,000 officers were assaulted. It's amazing how Obama used his time machine to make people assault and kill the police over a year before he became president. And I mention 2012 stats because your boys, agr2014 and Tony Bones, above, just like you, blamed it all on BLM and Obama, and certainly, they (BLM) have a time machine also, as they didn't even exist until 2014. What's also interesting is that after Obama became president, the number of cops killed and assaulted went down. Nutty how that works, huh?
