Recently the Yomiuri News on-line reported the following:
About the convict escape incident at the Hiroshima prison, a male (78) as the former prisoner who had experienced the penal servitude in the prison indicated that "with so many surveillance cameras watching etc, towards the prison officers, there could be a fanciful thought of asking whether was it really that 'there is no way to escape'?"
This male said "among those who had been in prison for a long time, there were many 'Who want to escape', and I had also thought of it several times. The difference was whether you do it or not."
In the playground of the Hiroshima prison, it was said that the shade of a nearby building had become a dead angle for the supervising prison officers; and it was being noticed and in fact it was concluded that Li the suspect also escaped from there, using it as the starting point.
The male also said "at repair site, while scaffolding were being constructed inside the outside wall, and at the same time there was only one surveillance camera to monitor (for signs of any suspected escape activities), that was unbelievable".
It was also said that "The prison officers at the time I was in prison had to guess what the convicts were thinking, and to grasp their feeling. Now, in order to avoid any collaboration, there was a tendency to draw a line with convicts, it was difficult to get hold of convicts' feeling".
I think to challenge the prison security system could be a reason to try to escape.
