The Counter-Terrorism and Border Security Act came into force two days ago with provisions including "create an offence of obtaining or viewing terrorist material over the internet. Incredibly, you only have to do this once!

https://www.cps.gov.uk/terrorismSection 3 updates the offence in section 58 of the Terrorism Act 2000 of obtaining information likely to be useful to a terrorist to cover terrorist material that is just viewed or streamed over the internet, rather than downloaded to form a permanent record;
How far reaching is this? Train timetables may be useful to a terrorist and God help you if you use Google Earth!
There are exemptions for academics and journalists. It seems that there are some defences including where a person "did not know, and had no reason to believe" the material contained terrorist propaganda. That's great but you have to argue that in court, assuming you can afford a lawyer and by that time could have lost your job, marriage, home, run up considerable debts to fight the case and had your children taken into care.
Even if you win you may find yourself unemployable in many professions in these paranoid times. If you managed to prove in court that you were the uwitting victim of a poisoned website or a hacker with malevalent intent or the like then perhaps you could get your police record purged - I don't know I'm not a lawyer. But suppose you stumbled across a prescribed site by accident? You might win your case by persuading the court that you have an impeccable background, are a member of the 'right' golf club, have no motive and suffer from 'old people and technology' ineptitude. But getting off by pleading you made a mistake may well leave you in the position of someone not convicted because the case was not proven - at least in the minds of potential employers.
Of course I doubt that the police have the resources to be chasing (for long) 'respectible middle-class' citizens who happened to hit a website of interest once or even twice with no other suspicious activities but what if you happen to be a young male muslim with a curious mind?
How many even know of this part of the act? I don't recall seeing it in UK news. They did give a fair bit of coverage of another provision - specifically "An individual found to have entered or remained in a designated area, unless for a legitimate reason such as being there involuntarily, could face up to 10 years in prison." Brexit dominates the news of course so much news doesn't get much airing.
This seems to me to be an ill thought out law with significant potential for miscarriages of justice. I assume here's a good chance that most MPs in parliamant, who approved the law, have not had many personnal dealings with the police and legal system and assume that common sense will prevail. Perhaps it does mostly but there have been many reports of cases that leave you speechless or shaking your head and muttering "I just don't believe it!".
