Trump shooter used drone before rally started, reports say

Reports from MSN and Wall Street Journal say the man who attempted to assassinate Donald Trump used a drone before the rally in Butler, PA.  Critics are calling out the Secret Service for failing to protect the former president and the people in the audience, calling it a major security failure. MSN's report says:

The gunman who shot former President Donald Trump in the ear at a Pennsylvania rally on Saturday flew a drone over the rally site a few hours before Trump took the stage, a source familiar with the matter told NBC News. The camera drone made by DJI allowed 20-year-old gunman, Thomas Crooks, to get an overhead view that maybe helped him plan his attack, the source said.
