Oh my, so much ignorance, so little time.
Let's see if I can do my part to educate some of the folks.
1. Referring to state trespass law as your recourse to dealing with census workers is completely pointless. There is this supremacy issue you have to deal with. OTOH many state and local workers have the same privileges - tax assessors, building inspectors, utility workers, and probably more. Call the law on them and watch what happens. Been there, done that, seen the asshat get blown off by LEO.
2. In the modern census, the census takers have nothing to do with the "long form." The form the census takers use is 4 pages with an addendum page, with a total of about 12 questions. The "long form" is mailed to a very small percentage of randomly selected people. The only people contacted by census takers are household that have not responded to previous mail contacts from the census bureau, or homesites discovered by census bureau survey teams that do not appear on address lists. FWIW, there are several long forms with different sets of questions which are intended to provide statistical validation to the census.
3. We didn't get a cool ID. We got a blank plastic ID form, a lanyard, and they loaned us a magic marker to write our own name down. I wish we had gotten a gov't issued ID.
4. We don't call in anybody, unless we are imminent threat of bodily injury, and then we call the local LEO on our own phone. Of course, I worked in an area that by and large had no cell coverage, so that wasn't really an option. As far as "calling in the big boy agents", way above our pay grade, but like millions of other American workers, we turn in daily reports that get passed up the line, and some people do get visits from the guys in the black Suburbans. Sort of like threatening the president on FB.
As far as telling the census worker, "**** you" that is what is recorded. You seem to think the census worker cares. All we had to do was document that we had attempted to contact people who had not responded to written contact from the census bureau. If you want your local census district recorded as 70% black and 25% Hispanic, more power to you. That's why the Dems are so adamant about getting "everybody" counted, everybody being illegals, blacks, hispanics, and the occasional disgruntled Caucasian.
The census counts warm bodies (it's one of those things in the U.S. Constitution, don't you know) and it's that count that determines congressional districts, federal funding allocations, local gov't districts.
5. Following up on the above, census workers don't try to "browbeat" anyone, because like low wage, hourly workers every where, they don't care. They make the same thing, they don't get a bonus for "browbeating" you into anything. They do have a pat little speech about how it is your obligation to participate in the census, it's for the good of the country, but, hey, if you don't you don't, and we go get a cup of coffee. In fact refusing to participate makes our job easier, because we just mark the form "RTA" and go on down the street. I'd like rather have a dozen rednecks in a row who didn't want to give "intel" to the gov't than one Hispanic family with 8 kids, grand mama, a cousin and his wife in the back room, and only one of the bunch can speak enough English to provide the info for the form.
BTW going back to sort of the original question (and I know that's not the ODT way) Georgia has a long tradition of the courts being very lenient to simple trespassers. As I note above, any intentional damage to trespassers or their property will come back on the landowner. That's why most timber companies will not let you cable entrances any more - some snot nose trespasser on a 4 wheeler hit one in NW Georgia (at Berry College I think) and cut his head off. The fact that he was trespassing did not keep the landowner from having to pay out big bucks.
