A bigger threat to this nation is the illegal influence campaign waged by the Russian government to affect the 2016 campaign. If Congress (or any government agency under this administration) really cared about the safety of the nation and it's citizens, they would do something PUBLICLY to mitigate THAT threat. I refuse to walk through metal detectors or fill out any more freaking government forms to rent vehicles of any king in this country. People get killed daily by moving vehicles. Using a moving vehicle as an implement of terror is not any different than using an AR-15 for the same purpose. It is amazing to me that my government would actually take steps against one and not the other. Must not be as much money from either the manufacturers or rental agencies influencing campaigns.
