WHAT WE WILL NOT COVER
1. Theft or loss:
from any building, land, premises or vehicle unless force, resulting in damage to the building or premises, was used to gain entry or exit;
You are only ever going to lose anything (accidentally) from a building, land or vehicle (the only time i can think this wouldn't apply is if you're swimming at sea in it!) there is never going to be any force so if you have the first (accidental cover), it MUST negate the second para otherwise the accidental cover is completely pointless and actually doesn't mean anything, which would be misleading and illegal.
If you have accidental cover, you are definitely covered against accidental loss from anywhere, which definitely doesn't need to involve a violent break-in!
