supposedly the reason junior Downing Street staff were fined

and senior ones weren't is because the senior ones declined to answer the question

a salutary reminder that, when dealing with police, always refer to the Pot Brothers At Law maxim - Shut The fook Up

I thought not answering the questionnaire was an offence, like those ‘identify the driver’ notices Although maybe it was returning it that was mandatory rather than answering the questions. 

It's like those White House staff that got fired because they admitted to having smoked weed on their security forms, after being told it wouldn't be a problem.

There's never any upside to being honest about this stuff. 

indeed

laypeople don't understand because they are brought up to cooperate and be helpful and (if white and not too marginalised) trust the police 

tbh as a non-criminal lawyer even I didn't understand and til fairly late on

the trick I guess is balancing it with their "attitude test"

"I thought not answering the questionnaire was an offence, like those ‘identify the driver’ notices"

Just thinking about this - does it remove the right not to incriminate yourself?
