I think a global approach needs to be made as far as all security measures are concerned, how they're financed, how they're applied, who does what, and not just knee-jerk reactions when things happen.
The air travellers security charge is collected by government, goes to the general fund, and then it funds CATSA. We don't know how much is collected and we don't really know how CATSA spends its money or if it spends it wisely. We have no idea.
