you line a big carrier bag with tinfoil, or you take something off the shelves and drop it into the bag of an unsuspecting person. Then when they leave the store it will trigger the alarms and you can walk through while the security guys jump on the other person.

You a criminal, Bro?

Unless you are planning to TAKE the item without paying, when you go through the cashier they will either take off the sensor or deactivate it

When you know you have an item that has some kind of sensor or beeper on it, what are some things you can do to prevent the items from beeping when you are going out the doors? I have heard of tin foil and I was wondering if those bags or coolers with the tin like linning would work? I have also heard of magnets turning them off? Are there any good tips on how to not make them go off or even any good tips on how to completely remove the alarms or sensors?
