ISA: is it being reinforced properly?

As all of usnoticed this few week
Tan Hoon Cheng, 33, a former graduate from the school of Communication, Universiti Sains Malaysia was taken from her home at Bukit Mertajam and told that she would be taken to Bukit Aman in Kuala Lumpur, but was informed of her release midway through the journey later. The reason she was picked up by the police is that she reported that Umno Bukit Bendera division Chief, Datuk Ahmad Ismail’s speech at a Permatang Pauh by-election ceramah on August 23 that Orang Cina cuma tumpang di sini sahaja (the Chinese are only “squatting” here).
The question here is: Why should she be detained under the act of ISA merely because she reported the truth?
This issue has brought a sense of injustice and hurt among people that the perpetrator has been let off scot-free while the messenger has been penalized. Datuk Ahmad Ismail was being suspended lightly from UMNO for three years ONLY, yet Tan was detained under ISA as the police believed her life was “under threat”, according to Home Minister Syed Hamid Albar.
The last bit to ponder on:

ISA= Internal Security Act or I Simply Arrest? Do think about it =)
