Well, here's something that has the possibility of biting someone in the ass

Oklahoma has a new law that makes it a crime to “fortify” a citizen’s home against possible entry by law enforcement.

State Rep. Sue Tibbs was one of the sponsors of a bill that makes it unlawful for “any person to willfully fortify an access point into any dwelling, structure, building or other place where a felony offense prohibited by the Uniform Controlled Dangerous Substances Act is being committed, or attempted, and the fortification is for the purpose of preventing or delaying entry or access by a law enforcement officer, or to harm or injure a law enforcement officer in the performance of official duties.”
...
The law states that to “fortify an access point” means to willfully construct, install, position, use or hold any material or device designed to injure a person upon entry or to strengthen, defend, restrict or obstruct any door, window or other opening into a dwelling, structure, building or other place to any extent beyond the security provided by a commercial alarm system, lock or deadbolt, or a combination of alarm, lock or deadbolt.

I understand the idea, though I think it's unnecessary; it's not like this is going to bother someone who's cooking meth or whatever. My concern is that some prosecutor is going to decide to use this against someone charged with something else because they had done something to make their home more secure.
