[billy]

2nd Amendment
The government may not infringe on the rights of the people to keep and bear arms.

thats out of context. you left out ;
A well regulated militia being necessary to the security of a free State, The government may not infringe on the rights of the people to keep and bear arms.

since then many amendments have been made.
such has you can't saw own a sawn off shotgun.

still we're leaving the topic behind,

i say a person should know how to use a weapon before being allowed to buy one , whatever the country what ever the laws. (which includes concealed weapons) that's me done.
