reform law that had the bi-partisan support of a majority of both houses of congress AND of individual No! But, TAA DAA....the T party nuts made it plain it did not have their support and....are you ready for it...individual No 1 changed his mind and Moscow Mitch made it clear it would never see the light of day. Check it out! Also remember that the Repubs controlled all of congress and the Oval Office for 719 days from Jan 20, 2017 until Jan 1, 2019. So who deserves the blame Buteye? HUH?
Now Buteye re-read your own post. It reads as if you saying that Hispanic immigrants had more to do with this event than individual No 1 or the rightwing nut case supporter of individual No 1 who pulled the trigger. Is that you intention? Oh by the way...back to the original question, where were all those ''good guys with guns''?
