BUT - if they were targeted last April, why weren't the security measures better? It's a well known fact that thieves will return about 6 months after their 1st attack to pick up all the new stuff that has been replaced on insurance.
Bedlam, if you read other posts on this forum, you will find that if a thief wants to get in he will. I have read or heard about cases where tackrooms were bulldozed because they were so heavily protected with steel doors and window bars. Another case reported that their steel shipping container had been opened with a set of firemens "jaws of life". The best you can hope for is to slow them down as much as possible.
