His comments reveal that he thinks that the people who died in Grenfell lack the 'common sense' that he has. I assume his 'common sense' comes from his sense of superiority which his background can't have done much to ameliorate.
The guy who defended him (can't recall his name now) was almost worse. Didn't he try to suggest that as JRM is a 'leader', he wouldn't have followed orders? Reveals a lot about both of them really.
In the end they are just trying to deflect from the fact that Govt policy of reducing 'administrative red tape' for businesses led directly to Grenfell
The people who died at Grenfell didn't die because firefighters made a 'wrong call' (in an incredibly stressful, complicated situation where they did not have all the facts).
They died because government policy reduced regulations that made building companies use appropriate materials even if they were more expensive and time consuming to put in. The people in Grenfell tower were killed by politicians and senior decision-makers in the construction industry putting profit before people. They were also killed by the various people in local government and organisations that refused to listen to the safety concerns of residents who repeatedly highlighted problems with the building.
A crime as old as time and very rarely punished appropriately, because the perpetrators are rich and powerful and the victims are not.
We know what happened at Grenfell but instead of taking this on board and making changes that prevent it happening again (I think there are still buildings with the same cladding with people in them now), the Govt tries to blame the people on the ground, even the people who ran into a burning building to help are to blame now as their help was apparently not 'good enough' , or at the worst case the victims blamed because they 'took the wrong decision'
The usual obfuscation and deflection by people in power, when a tragedy is clearly a direct result of their decisions
