They have an easement to their cable box if it's on your property even if you don't subscribe. I'm not saying the guy was legit, but if he was, you can't deny access to their equipment. If not on your property, the point is of course moot. Secondly, you do not
have the right to use deadly force against simple trespass in CO or any other state. Only reasonable force, and if he was legit, you don't even have that right in the scenario I described. I'm glad it worked out, but deadly force under the Castle Doctrine only applied to someone in your domicile, not on your property.
I don't disagree, but I do believe that any company that routinely needs access to homeowner yards probably has a system in place to deal with suspicious home owners. They would of course try to limit unease with things like a logo branded truck and/or having the home office call you and verify that they do indeed have work in your area.
If I was a betting man I'd say Nate would probably hold the man at gunpoint until the police arrived and confirmed he worked for Comcast or arrested him for trespass. With kids at home it's even more important to have your head on level, if he [Nathan] was to get arrested, I think the girls go to Social Services until they find his DW (I may be wrong, but I'm sure I've read something like that once)- that's something that as a parent I have at the back of my mind at all times when I carry.
I'm with Nathan on this one, this guy was too reluctant to provide proof of a need for access, and the fact that he apparently went on his way without ever entering the yard seems to paint him as anything but a legitimate Comcast employee.
If Nathan wanted to push the issue, he could call the local Comcast office and check to see if they had any work orders being done on that day/time (Comcast workers note arrival times, it would be easy to pinpoint this instance). If the answer is negative, then at least Comcast is aware of someone using their name as a front for possibly malicious means.
