"The act of the 25th of March, 1813, makes it a misdemeanor to be "found with a concealed weapon, such as a dirk, dagger, knife, pistol, or any other deadly weapon concealed in his bosom, coat, or any other place about him, that does not appear in full view." This law became absolutely necessary to counteract a vicious state of society, growing out of the habit of carrying concealed weapons, and to prevent bloodshed and assassinations committed upon unsuspecting persons. It interfered with no man's right to carry arms (to use its words) "in full open view," which places men upon an equality. This is the right guaranteed by the Constitution of the United States, and which is calculated to incite men to a manly and noble defence of themselves, if necessary, and of their country, without any tendency to secret advantages and unmanly assassinations."

I guess the "Gun Rights Crowd" are going to have to push for open carry.
