G20 demonstrations

The legislation doesn't specifically target photography, it covers "eliciting, publishing or communicating information" so could theoretically cover drawings as much as anything else. Having said that, it's only an offence if they can prove that the information is "likely to be useful to a person committing or preparing an act of terrorism" and proving you had a reasonable excuse for collecting the information is a defence.

Oh come off it ! Do you really want me to list all the abuses of the current terrorism legislation ! Of course this will be abused, It is the job of the police and the courts to interpret how this law is applied.

Of course that's not the real issue, the chances of a court convicting anyone for photographing the police in a situation like this seem remote at best, rather it's the concern that the police will abuse the legislation to harass and arrest photographers, even if no charges are ever brought.

Agreed.
