Stories abound of retired officers being harassed, or even arrested, for carrying concealed firearms in compliance with the Law Enforcement Officer's Safety Act (sometimes called HR-218) in some jurisdictions.

Are MPD Officers aware of the law and do they honor the right of retirees who might be found to be carrying a concealed firearm?

I ask because of a proposed trip to DC and I am in the habit of carrying a concealed weapon.

Thank you for any responses.
