As others have pointed out - once the precedent is in place, what is stopping them from deciding that some other piece of software superficially matches the law close enough that the police will ding you for it? After all, this is policing 101, where they use whatever laws are on the book as leverage for something totally unrelated to the laws they're using.
Having a look at the wording on offer:
- An offence of making, modifying, supplying, offering to supply a specified article where a person has reasonable grounds to suspect that it will be used in any serious crime.
- An offence of possessing any specified article where a person intends or, has reasonable grounds to suspect, that it will be used in any serious crime.
Every time we get new laws like this, we take a step towards the police being able to arrest anyone, for any reason, at any time.
