Yes whatever will you do without high capacity magazines. Please quote where the constitution says you have a right to them.
You should take a course on the Constitution. Your post agrees with what Lame Duck President Obama THINKS the constitution SHOULD say and not what it dies. President Obama, and obviously you, believe the U.S. Constitution should enumerate what the government must do FOR the citizens. Instead, the Constitution was designed to LIMIT what THE GOVERNMENT MAY OR MAY NOT DO. Anything addressed in what the government may do is left to the states.
So you mission, should you accept, is to show us where in this amendment, the government has the right to limit them.
Text of the 2nd Amendment
A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.
