SENATOR ANTONIO F. Trillanes IV on Tuesday said his residence was being surveilled by “suspicious” cars following the presidential proclamation voiding his 2011 amnesty. His office released to media CCTV footages dated Sept. 11 of a vehicle stopping in front of his house for a brief period before speeding up again. “The behavior is highly suspicious and there are hallmarks of casing activity. This is not merely harassment or intimidation because they were not meant to be seen… Maybe they are calculating whether they will enter or whatever they want to do,” he told reporters outside his office. Mr. Trillanes previously said motorcycles trailed his vehicle last week after he planned to leave the Senate premises. He has been holed up in his office while his case remains pending before the Supreme Court and the regional trial courts. — Camille A. Aguinaldo
