That is a good point. Though his reckless use of twitter has now led to a country declaring war on us. That is dangerous for all americans.
JGP, Obama never tweeted to kill a cop or start a fight, Trump actually encouraged people to throw punches. Also linking Obama to BLM is akin to linking Trump to White Supremacy. Both are equally wrong associations.
Obama never had to tweet kill a cop or start a fight.
Those cop killing leftists in Dallas and the violent protesters at Trump rallies knew what they had to do....and you wonder why Trump said to punch back.
