answer to my last question

How often does criminal in the death row try to escape? And how many of them actually succeed?


Criminals rarely escape from prisons not even once in a year.
Much less than once a year.
Though there are various ways that they escape.
There are some cases that they succeeded though most of the time they get captured very fast.
One way is that they escape during the police transporting the criminals to other place.
Other way is that they break the grate of windows and escape or making holes in the wall.
