Notably the examples on the page you linked appear to involve illegal acts (tampering, threatening, etc). Letting someone out a different door (neither party is trespassing) doesn't seem to rise to that bar. Just as I'm not obligated to call the police to report something I don't see how I can be obligated to force my guest to use a particular door for the convenience of the police. It isn't my responsibility to actively facilitate their actions. It would never have occurred to me (and doesn't seem reasonable) that obstruction could involve indirect (relative to the government process) actions. I could understand "aiding and abetting" if I was actively facilitating the commission of a crime but I don't want to live in a country where mere avoidance is considered a crime. "Arrested for resisting arrest" gets mocked for good reason.
