All potent steps to stop the radicalisation but it misses at tackling other causes of the problem. What needs to be done is re access the reasons for the sudden upsurge, it is not like there was a sudden button pressed and radicals started jumping out of the water. What are the triggers which started this? Isis has been going strong for some time now, before that there was a lot of militancy in the world which Bangladesh was not affected by.
One needs to step back and re access policies which are driving the youth to these acts. Till triggers are removed, no amount of monitoring will stop more radicalisation, the best it will do and this is the most optimistic view, stop the radicals before they cause any mass casualties...
One needs to address root causes, which also stopping radicalisation of the youth. Just doing one without the other will leave loopholes which will end up in lose of human life, which is both heart breaking and too be severely condemned by all.
Hoping that no more innocent people die and Bangladesh matures.
Before 2013, there were no social divisions that we see today. It is also worth noting that there is a zero-sum game being played within the politics of Bangladesh at the moment.
During the Shahbagh movement, by the demanding execution of Kader Mollah (along with a bunch of other conditions), there were
some within that crowd that insulted Islam and the Prophet Muhammad. The atheist, Ahmed Rajib Haider (aka Thaba Baba) was murdered at the time. It was from there that these secret killings started to expand into a more broad target list.
Rajib was praised by Sheikh Hasina and given an Islamic funeral despite his apostasy. This enraged the Islamist community - Namely Hefajat-e-Islam which was a little known ultra-conservative group. Though, they were largely not political in the past. They did come up with their own 'Shahbagh', only to be violently suppressed by the security forces. Now that is bound to create a lot anger.
Ironically, Sheikh Hasina now urges people not to hurt people's religious feelings. Additionally, the leader of
Gonojagoron Mancha, Imran H Sarkar had an apologetic attitude in regards to the atheists who were continuing their online activities - A move I believe was both dangerous and counter-productive given the country's mediocre law & order and political situation.
Even more so, our prime minister blamed these secret killings on the opposition. She treated the horror at Gulshan the same way. Why she does this? No one knows.
So like I said, these social divisions in Bangladesh weren't present before 2013. The Arab Spring and the resultant events are an eerie reminder.
