The freezing also shuts down the electrochemical reactions that power the bomb’s battery, slowing down or stopping the timer and reducing the power to where it hopefully can’t generate enough of a spark to set off the detonator.
 
But then you’re left with a bunch of frozen explosives, of questionable quality and stability, that will eventually warm back up. So after freezing it, they normally take the frozen bomb out away from people, inside a reinforced concrete barrel with walls a couple of feet thick, mounted on a trailer. If safe, they then take it out of the barrel, move the trailer away, and shoot the bomb using a remote-controlled gun. If they can’t safely get it back out of the barrel, they just blow it all up; the trailer and barrel are only a few tens of thousands of dollars, and smaller bombs may not even destroy them. And if they can’t safely move it in the first place, they’ll just sandbag around it and shoot it where it is. The point being that blasting it into many smaller parts that are still cold will maybe prevent some of them from detonating (especially if you blast the detonator away from the bulk of the explosive), and reduce the shock front velocity from the pieces that do detonate, resulting in a smaller overall explosion. Most high explosives will burn without detonating, assuming they don’t detonate because of a shock wave. In any case, the power of a given chunk of explosives is easily calculated, and most man-portable bombs aren’t all that powerful. You don’t want to be near them with exposed flesh, but a wall of sandbags and some distance between the flesh creatures and the sandbags can turn a lot of bombs from a massacre into just a bunch of broken windows and ruined paint.
 
Actually disarming a bomb at all is risky, so they generally just buy time and fix the damage after.

Actually, from what I heard, the bomb squad usually doesn’t cut wires to shut off a bomb.
 
They usually FREEZE the bomb using liquid nitrogen.

Why am I imagining some Luna cosplayer out of costume going talking to someone and being all “Ah yes. Let me give you my card.”

@Nightweaver20xx  
Except the red one. You should never, EVER cut that wire.

@WingbeatPony  
It’s like a bomb, and you have to figure out which wire to cut. PROTIP: Cut ALL OF THEM.

You mean the thread with Hasbro smacking the C&D at Jan Animations?

Don’t worry about it, several people got the same thing.  
That was just a thread that needed defusing fast.

I’m throwing my money at the screen but nothing’s happening!
