It's really very rare. For the most part, people are exercising a certain amount of caution. Every so often a dog will drown in a canal. Mainly it's canals but not beaches.

A stop light not a caution light but a traffic light where they have to stop and let people turn, go straight, whatever.

If people admit using cocaine or go into rehab we give them a caution. It's very likely she'll be interviewed ... even if just for intelligence purposes.

I think we wanted a situation whereby people were exercising their rights with caution, but these ones over-stepped their boundaries.

I caution people in these categories if they are contacted, they should not reveal biographical or personal information - even if an electronic communication looks like it comes from us.

I think people are cautious, but I think caution is different from resistance. Universities are slow to change. ... I think there is an institutional crisis when a new field emerges and comes into its own.
