Arson attacks on transports

I am deeply saddened and touched by the suffering and death of arson victims in recent weeks in Bangladesh. This made me think, how could we prevent arson attacks by the terrorists? One of the reasons of this kind of continuous assaults is that the perpetrators can flee unchecked as security personnel are spread thin in highways and city roads.
I suggest the government recruit an adequate number of cops to beef up the highway police squads and give them transports and proper supplies. If we have 20 properly armed cops in every kilometre in plainclothes, the terrorists would be deterred from committing arson. From cost perspective, this will be lower than what is incurred through people's death, suffering and national economic loss.
It may take time to recruit and train this kind of a big force. In short term, we may depute Ansar and VDP reserve members and place them under highway police department. Also, retired but physically fit defense, BGB and police officers and Jawans can be offered 1-2 year of contractual service to overcome the current manpower shortage. If there is not enough reserve personnel available, hire some workers from "Food for Work" programme for 6-12 months and give them short training to be employed. Let them work under the highway police and guard the transportation sector from the arsonists and terrorists. Hope government will take proper action to safeguard people's life.
