1. get rid of all firearms (no gun powder), and buy a really good pellet rifle.

If the LE crowd comes up wants to be a pain, they can send you to jail for 5-10 years for just having the firearm (5 years), if you pull it out (7 years) and if you use it (10 years).

2. Think if you were a crook, how would you get in and what can you do to protect your crop.

3. Set up a tent and put a sleeping bag in it.

4. Check with any of the local dog rescue groups and see if they are looking for foster homes for any of their dogs. If so you might look for a very noisy dog and at night secure the dog in the middle of your garden, within a ear shout of yourself. After your done, maybe you'll do the dog, and yourself a good thing and you'll make a permanent home for the furry friend for his/her good service! If not, typically you can return the dog.

You area has become a vacation spot for theives, good luck and be safe!
