What you see in movies and what really goes on are two different things. Hollywood gets a few tidbits and turn it into a big to do. Use that A&P for example let's put try it a little different outside of Hollywood. Stores closes 3-4 guys a scanner and a couple of radios if your really just a starter crew maybe you opted for a simple car horn instead of a radio. 1 guy stays outside and monitors the perimeter for random patrolling cops and keeps his ears on the scanner. The other guys bypass the alarm enter the building thru a back door. They find the safe and cut it open with a K-12 saw and a diamond carbide blade. Bring an extra blade & rubber belt it the event either break. That's it no swinging from the ceiling or using Semtex.
