I think the difference is "armed" verses "guns drawn". You can't expect anyone to raid an allegedly illegal operation or building or confront someone without at least having a weapon on them. A gun in my face or pointed at me without me presenting any danger to that person would be unacceptable. It's not easy to properly assess a situation when you are waving a gun around. Requiring an officer/agent to draw his weapon would give him a few extra critical seconds to judge whether or not someone/something is an actual threat. If an officer/agent busts into a room with a gun drawn and I set down a water bottle too fast or startles my 30 pound dog, then I or my pet has the chance of being shot unnecessarily, that's unacceptable and is something that needs to change.
