What do you do if someone denies the test? You can deny them entry, but if they protest or decide to force the issue, then the police have to deal with it. Then if the police get sick, they have to self-quarantine, and what do you do when you don't have the power to enforce the test?
Even if we managed to dress up our entire police force in hazmat suits to reduce the risk of infection, they can still infect people out and around the building. Turning away someone doesn't mean we're reducing the R0, we're just moving someone that's infected around. Given that there are asymptomatic people (and a certain number of people that would likely claim the test is a false positive or fake), all we're really doing is encouraging more people to gather in a single location as a potential infection vector.
Let's assume next then that somehow we had an automated solution. All the doors to said buildings are locked unless you complete a saliva test to go through. Barring the huge logistical concerns, we're still dealing with potentially infected people spreading the virus on surfaces and areas that people are travelling to and from.
