I think some terrorism laws enable preventative measures. Some of our terrorism laws say that it is an offense to ….
- commit a terrorist act
- plan or prepare for a terrorist act
- finance terrorism or a terrorist
- provide or receive training connected with terrorist acts
- possess things connected with terrorist acts, or
- collect or make documents likely to facilitate terrorist acts
Suspected terrorists can be ‘preventatively’ detained for up to 14 days, and they can be detained for questioning for up to 24 hours.
Also they can be subject to a court-ordered control order for up to 12 months, which can stop them from …
- being in certain areas or leaving Australia
- communicating or associating with certain people
- owning or using certain articles
- carrying out certain activities, including work
- accessing certain forms of technology, including the internet.
And may require them to :
- remain in premises between certain times of each day
- wear a tracking device
- report to someone at a certain time and place
- allow themselves to be photographed.
Of course, they are entitled to a lawyer and all other humane treatment as well.
