also, has nobody questioned (going with my assumptions that it was a heavy machine gun) how a HMG and 9 other firearms probably passed through hotel security for 3 days.
have you ever been to a hotel? the extent of hotel security is like a bouncer at a club, completely reactive and if anything serious happens they just call police. they (usually) don't have metal detectors, X-rays, or check the contents of your bags
im not sure about this specific hotel, but that's usually how it goes
