I agree with what you say about it being ineffective because you can conceal it inside of your body, that means it’s a completely useless security measure. Wonder what the argument was to implement it then in the first place if it’s not really adding to security.
It’s a disgrace though that this is already being used, it doesn’t solve anything. Terrorists will always find new ways and different targets. Life is vulnerable.
There has to be a balance between security and privacy. This is clearly not the case with these scanners. You can see way too much on these pictures. If this is implemented, terrorism has won already.
