The point that he noted requires a more closer study.Also his can be called as safegaurds rather than tactics.I like what you qouted by MLK.
Before the advent of 498 woman were indeed murdered with utter disdain and every alternate day the newspapers would have atleast one incident of dowry realted murder.(not saying it is not occuring now ) and then a law needed to be made to curb dowry related deaths (murders) and indeed a law called 498 was enacted but in such a lopsided way that though it may not have the seriousnes of sec 304 it was enacted as a criminal case.By making this a criminal case the onus to enforce it fell on people with dubious background who themselves are the most corrupt.I think you will be surprised that FIR can be filled with amount as low as Rs 200
By making it non compoundable non bailable and cognizable provided more ammunition and a legal licence to these corrupt people to extort money.It was enacted in such a lopsided manner that only a mere accusation led to arrests.
People apall silence because the neighbours house is on fire and not theirs...they will only shout when fire engulfs their house as well ..and when this happens a collective voice will be raised...till then the sufferers will suffer,the saviours will try to save the sufferes,the people who can will be savouring the poisonius fruits of 498
