Picture this.
One day, your doorbell rings. At the door, you find a bunch of police officers who say they need to speak to you regarding some unrest which took place in your city/town/village a few months ago. Being a law-abiding citizen, you go with the police to the local thana.
You answer their questions about your whereabouts, you inform them of how you participated in protests against what you believed to be a draconian law or explain the work you do for helping marginalised communities. No incriminating material is found on your person, your bank and phone records show no connection to any wrongdoing.
You’re still arrested by the police, who say that they believe you have committed an offence under the Unlawful Activities (Prevention) Act 1967. They say you’ve been involved with planning and plotting terrorist activities, and that they have evidence to back this up. You are not provided with this evidence.
