It is bad enough to inflict pain on another being, what more inflicting it on a monk. What were they thinking of? Brutality in prison is not some new news. They just took it upon themselves as part of their daily "work" - someone gets slammed behind bars, refuse to co-operate with the so-called laws, beat the daylights out of him to squeeze information. How brutal.
Poor guys; they did not understand the law of karma. All the more reason why we should pray for the ban to be lifted, so that the dharma may flourish there.
