A small snippet from the article includes details for a decent number of the deaths:

Among the 518 dead, 490 were male, 21 were children and 16 were security officers, Othman said, adding that 197 had died from shotgun wounds.

But he explained that the death toll could be higher as some victims had been buried without the authorities being told.

More than 2,000 people were injured, including 120 security officers, he added.

I’m all for an age cap. It should be dynamic and based on some sort of percentage of the average lifespan of the population in their area.

It would provide a good incentive for them to vote in/pass legislation which would help raise the overall life expectancy of everyone.
