The President appears ready to infringe on the 2nd amendment. It might help the president to become more familiar with the definition of infringe if he were to write the definition 1000 times on the chalkboard. Here is the definition - so he doesn't have to look it up. infringe: act so as to limit or undermine (something); encroach on.
The 2nd amendment says "the right of the people to keep and bear Arms, shall not be infringed." Banning certain guns and limiting their use is, by definition, infringing on our right to bear arms. 1000 times is probably not enough!
