sentence him to what he had sentenced others with that bomb. find who were funding him, sheltering him, how he got that material, it has to be a network, it cant be a courier of neogel arriving at his door step. book them all, go where its necessary to go - it can be a mullah who incites violence or a local politician, a businessman patron. get them all or whoever is responsible. only then the police claim theyve done the job.
