Despite what the factually challenged GOP would have you believe, this is a historically low crime era in America…

What’s tremendously aggravating is that Giuliani, and, in turn, the GOP, speak about making America safe “again.” He said that Trump “will make America, like the president I worked for, Ronald Reagan, once again be the shining City on the Hill.” But here’s the thing: During Reagan’s presidency, which lasted from 1981 to 1989, America was way more dangerous than it is today. In that era, there was an average of 20,377 murders a year in the U.S. There were 14,249 in 2014, the latest year with official FBI data. Meanwhile, the U.S. population has grown from 229 million to 310 million, a 35 percent increase, driving down the per capita rates. There’s also never been a safer time to be a child in America, and while an average of 101 police officers were intentionally killed every year during Reagan’s presidency, the annual number is just 62 under Obama — the lowest recorded amount.

It is a manufactured fear- it is only being sold to the stupid in order for Trump to get votes by calling himself the law and order candidate…

It is similar to the crass way the GOP exploited Ebola prior to the mid-term elections:

Isn’t there a term for zealots that attempt to create fear in a population in order to further their political goals?
