Passport queues and what’s the point?

[Uplinker]

........So the question I ask is, what’s the point of all this? What is the threat of a tourist travelling to a holiday spot? Is this not an opportunity to make the travelling experience significantly easier?.......

How does anyone except you, know that you are an innocent tourist going on holiday ? A criminal is very likely to hide what they are doing and will probably travel from A to B to C to D, via holiday destinations to hide their intentions, instead of going A to D directly.

Also, criminals or people of interest leaving a country might have an all ports bulletin issued by the police, so passports have to be checked for this.

As far as checking computerised tickets, a criminal can probably fake their personal details on these, so the passport must be checked to confirm identity. (Passports can also be faked of course, but it's much harder to do, I would imagine - and hope !).
