First I'll agree that situational awareness is the first layer of defense and can be practiced with ease and minor inconvenience.
I don't know what website you can use, but perhaps a Google Earth might show long term encampments? The more remote locations don't usually have a lot of updated imagery, so might not help.
I'm not familiar with State Trust land designation? Is that a state-based analog to BLM or National Forests? Which LEO is in charge of that area?
A casual conversation with a LEO where you convey your desire to camp and stay out of the "bad areas of town" could reveal a lot and offer alternatives if necessary.
There is a big difference between asking where you can be safe and relaxed versus "reporting" a suspected problem.
IMHO, if people are having troubles and have taken to tents, don't add to their burden if avoidable ;)
Maybe you'll find a much better area for recreational campers not to far away :C
