Right, because it's prohibited. They won't put in the checked bag. They will alarm the bag. The bag will have undergo into the secondary screening for further inspection. THey will open the bag to find a suspicious items. The grenade are very extremely dangerous and it's not safe in the checked bag. They didn't notify the police. I believe they didn't have security breach. They did not called the bomb squard.
