For starters, the Belgian police allowed the match to kickoff without having nabbed the terrorist. He was roaming freely for quite sometime! It was the Swedish players who took it upon themselves to not play after HT( which is when they heard the news)
There were so many lapses, when you organise an international match, the security level should be anyhow elevated. You have foreign fans visiting your country & it is your responsibility to protect them!
They need to know how did he get arms so easily in Brussels? Why did it take so long to nab him?
If this has happened in Qatar during the WC , the whole international/ western community would have been up in arms blaming the security arrangements, so why not for Brussels? If their is an incident/ loss of life the security system must be questioned and held accountable.
