why dont they use cctv to see what flight they were on??

???? did you actually read the post you're responding to?

In the 90s...
 

It was like Crufts Dog Show on the jetty arriving on anything from Colombia...

I always manage to get the attention of the dogs at US airports because the carry-on bag I usually fly with is the one I use to cart stuff to and from work and it often contains fruit. I don't think they've ever asked me to prove there was no fruit in it, the explanation of prior existence of fruit seems to be enough.

I remember seeing a comment once where someone reckoned that a significant proportion of passengers arriving in the UK from the West Indies were probably carrying something of dubious legality.

Brazilians believe in reciprocity, the visa requirements for a foreigner to visit Brazil are exactly the same as the visa requirements for Brazilians to visit the foreigner's country. When the US started fingerprinting Brazilians on arrival, Brazil responded by fingerprinting Americans on arrival.

Don't be surprised if Brazil responds in kind.

Possibly a few too many Brazilians pretent to be Portuguese the moment they arrive landside in Europe.

Inbound flights in Brazil are often met at the gate by the police, mostly flights from Africa but occasionally flights from Europe too. I suspect that there is a surprising amount of intelligence shared by the various agencies involved, both inbound and outbound.

Nobody here gets upset about it, unlike the fingerprint spat, so there are no demands for reciprocity.

You're average Brazillian isn't going to be any more successful at pretending to be Portuguese than your average American can pull off pretending to be English. Brazilian Portuguese is as different, and different sounding from Portuguese Portuguese as is American English and British English.

At airports like London Heathrow the police who have airside passes are there partly for protection against terrorist attack and so are armed. So it's not that the police are chosen to attend aircraft for immigration or drugs policing are chosen because they are armed, but because they have airside passes and are in the airport.

That is also why when a passenger starts arguing a bit too much with the airline staff and won't calm down, armed police arrive. They don't need the arms for this problem, but they happen to be armed for their other duties in the airport.

...and there is nothing more annoying.
Coupled with Pearson's general ineptitude and drawn out entrance experience it's an excellent time!

I've never had a problem at YYZ, granted it's been 5+ years since I've been there...

In Brazil, there is a Kleptocracy. An ex president jailed (corruption/$ laundering)
 

Many people leaving the country. (tourist visas issue?)
Probable at these airports: Tight screening due intel. leads
Increasingly volatile situation due elections this year
