The people who complain about heightened security never have a better proposal. This article is pure pandering with no balanced opinion of the fact that there could be credible motivations to ask for this.
Sure security is bad in other countries. I've had to remove everything from my bag in several airports, but America is still somehow the worst in spite of that. Fuck the TSA. When I do leave the US, I take a train to Canada and fly from there. Their security is mostly the same, but at least I feel like I can't complain since it's not my country.

That is precisely what happened in the Brussels bombing. The Manchester bombing also happened at the general entrance of the arena, not inside.
