CharlesWayneCT is correct in post 2 - a requirement that carrying arms be done openly would perhaps be unwise, but it would not be a violation of the second amendment. The second amendment recognizes a right to bear arms, but not necessarily a right to conceal those arms while bearing them.
Bear: to hold or carry (oneself, one's body, one's head, etc.): to bear oneself erectly.
Reminds me of that commercial from Ally bank.

“Would you like to go for a ride on that bike? Okay!” Kid tries to leave the little enclosing lines drawn on the floor. “Whoa! If you want to take the bike out of this space, I’m gonna have to charge you a penalty.” “You can’t really ride in this little space.” “You can’t ride really FAR, haha.”
“Even kids know an offer shouldn’t come with ridiculous conditions.”
Same with rights.
You want to carry openly in the city where any mugger can see your weapon and grab it? Or just go about unarmed? I don’t. In some places I wouldn’t get much farther than that kid in the commercial, carrying openly.
