Assume Adam, Esquire, is working in Colorado. He has an office different from his home. Let's say Downtown in a sleepy town that has no extra gun control laws. It's 3 AM and he is working on the filings for the next day, the light visible from the front street, but not the back. His trusty Taurus Public Defender is sitting on a pile of files next to him.
Butch decides that he wants to break into the office of Mr. Adam to try and steal something. Butch picks the lock and sneaks into the front room of the office. He entered from the back of the building and didn't see the light, so is not suspecting someone would be there. As a result, he isn't very silent.
Adam hears the commotion and guns Butch down with a snarky remark of "Make my Day".
He knew that Butch committed trespassing besides the breaking and entering - nobody is allowed to be there but him after closure. And Adam reasonably believes that Butch either is attempting to commit theft, destruction of property, or might target Adam to do him harm. That qualifies for the Make My day.... if it's in a dwelling.
But is a closed office after service hours, but separate from the permanent residence, a dwelling that allows to invoke Colorado's “Make My Day law” CRS 18-1-704.5?
