Coronation Street

[Mike]

Why on earth does Sharon have a taser? Huh?

She's doing dirty work for a drugs gang, not really that hard to question

I'm not sure a Taser would be the best weapon for a drugs gang to give to someone; each cartridge sprays confetti with serial numbers from it everywhere and it wouldn't take the police long to find out where the device was sold and who to (not that you can buy them in the UK, so assuming that it's a stolen one from the local Gendarme or stolen Line of Duty style, you'd still be able to find where it was from and then work out through audit trail who signed it out), they also wouldn't make you unconscious and the probe spread shown in the scene wouldn't put you on the floor...
