I would believe that in those spheres of power they would have booked a hitman with better hardware and training.
His pistol could not properly cycle and he took quite long between shots.
Also he had the possibility to move up to the guy and shoot him in the back of the head to save some time but preferred to shot multiple into his back from further away.
For me it seems more likely it was an act of Vigilantism.
It happened in France for example.
Now it would not be public killings by guillotine of course but multiple independent attacks by ied/gun/fpv against guys like that ceo are surely thinkable.
Worst case there is they have to pay for it and more money goes to working people. If they're in a serious threat of danger, I'm sure security costs increase too.
I guess the logical progression is to go after the most accessible level...meaning eventually the office workers would probably be a target, which isn't great.
That, or people go after, like, their extended families instead...which isn't exactly great either...
Maybe flooding a country with firearms and putting them into its constitution isn't such a good idea
