Most current law on law enforcement carring weapons off duty?

Most agencies encourage or require off-duty carrying of weapons by law enforcement officers. A recently-passed law allows off-duty, sworn and certified law-enforcement officers to carry concealed weapons any place in the U.S. (it is not prohibited by law to carry, but there may be restrictions on specific sites, such as court houses, churches, etc. that will impact the off-duty carrying out of the officers home state). In all states I am aware of, off-duty officers of that state may carry weapons anyplace they could carry them on-duty (which is everywhere).
