Random thoughts.

After you get better doors, look for the next weakest link. Probably your windows. It is unlikely you'll be able to make it so they "can't get in", but hopefully make it more work than it is worth.

Also, take a look at http://en.wikipedia.org/wiki/Lock_bumping Look at getting locks that are resistant to this method since it is fast and easy.

For windows, they have films, or when you replace your windows, consider getting ones with laminated glass. You can still get in, but it is more work.

You'd probably be better off letting the police clear the house unless you had an immediate need (wife/kids in the house).

Good luck.
