It is far from the first time that gun-rights advocates have aimed accusations of hypocrisy toward those who call for stricter gun control while receiving armed security. In 2016, gun-rights groups called for Democrats to bar all armed security at the Democratic National Convention.

“Gun owners are demanding that the Democratic party practice what it preaches,” read a petition from the Citizens Committee for the Right to Keep and Bear Arms. “If a political party believes that guns do not make us safer, they should set an example by rejecting any and all forms of armed security at their convention.”

Similar attacks have been used against celebrities who have called for tighter gun controls while enjoying protection by armed security. It has been noted, though, that the likes of Sanders, and others calling for stronger legislation, have never called for firearms to be taken away from trained professionals, but rather to expand background checks to ensure they don’t get into the wrong hands.

Sanders, however, has a murky history on gun control legislation, something that was used by Hillary Clinton to attack him during the 2016 Democratic primary.

Students walked out of school and took to the streets Wednesday as part of growing calls for gun control in the wake of a shooting at a high school in Florida last month that killed 17 people.
