Is it possible for a 12 or 13-year-old boy to have to go to jail ?

im 13 and i know the names of all the officers in my local police station for all the times ive been locked up...hahah no

yeah it depends what they did but its tottally posible 4 1 2 go 2 jail they just cant be charged for as long sense there a minor

not sure about jail but i no from the age and 10 and above a crimial charge can be taken place.

Different countries have different laws. I suppose in some parts of the world this could be possible.

Yes, but it wouldn't be in an adult facility. There are juvenile facilities for this.

of course, but it would be called juvenile detention.
