Acid attacks on children must be punished by severe custodial sentences

The Worcester acid attack by men on a three year old boy must be punished severely, which
 should  deter others. They should spend many years in custody, locked away under rule 33, for their own protection, being despised by prisoners and public. This would send a strong message that we will not tolerate these acid attacks, particularly on pre school children, innocent infants. Disgraceful!
