This Secret Service White House guard with P90 submachine gun protects Obama and his family. His fully automatic weapon uses 50 round magazines.
When it comes to protection of your family, Obama objects to semi-automatic weapons and 11-round magazines. Not very equitable, it is?
In the grand scheme of things, the P90 submachine guns aren’t significant. Obama’s Praetorian Guard also has six-barreled 6000 rounds-per-minute 7.62mm machine guns with them. Since these were made after 1986, no way you, a lowly civilian, can have that!
