It's evidence of nothing, and most certainly does not point to any reasonable or logical conclusion. Do you also believe the US Air Force is not a US government agency? http://www.airforce.com/I was not suggesting it, and maybe my sarcasm didn't make it clear, despite my reference to the Constitution and legislation, rather I was flat out stating the US Postal Service is in fact a government agency.Are you suggesting that the USPS is an actual governmental entity?Well apparently you can't tell anything beyond a website extension.As far as I can tell . . .I wasn't arguing that point, merely addressing your completely false assertion that the USPS is not a government agency.Do you think there's a good reason why carry should be a felony in a post office any more than it is in a FedEx or UPS building?Again, that is simply not true.Effectively, the only difference between the three is that one was originally established by the government, but has effectively become a separate entity, and the other two are fully private.I already offered a logical reason, and it begins with Article I, Section 8 of the Constitution of the United States, which reads in pertinent part, "The Congress shall have Power . . . To establish Post Offices and post Roads . . ."Sarcasm away, sir, but please, offer a logical reason why you think post offices should be considered federal buildings.
Further, Title 39 of the US Code (aka federal law) clearly shows that the US Postal Service is a government agency. It's long and boring, but feel free to read it for yourself: https://www.law.cornell.edu/uscode/text/39/201
However, I'll make it real easy for you, and quote the simplest, most direct portion, which shows your rantings on this topic are completely false. Title 39, Section 201 of the US Code, in it's entirety, states, "There is established, as an independent establishment of the executive branch of the Government of the United States, the United States Postal Service." https://www.law.cornell.edu/uscode/text/39/201
So it's your own ignorance that prevents you from understanding why USPS offices qualify as "federal buildings."
