No one will forgive the government if the Pattaya riot reoccurs, Chuan Leekpai, former Thailand's premier warned on Wednesday.
Chuan, who is now the chief advisor of the Democrat Party, was also former Democrat leader.
In mid-April, thousands of the anti-government protestors stormed into the ASEAN Summit venue and its related meetings in central resort town Pattaya, resulting in the cancellation of the Summit and its related meetings.
"If the Pattaya violence repeats, no one will forgive (the government) since it strongly damages the country," Thai language news agency INN quoted Chuan as saying.
Many people have criticized the government's plan to enforce the Internal Security Act aiming to ensure law and order whenever the anti-government group holds a mass anti-government rally.
Chuan, however, said from the government's point of view, it will become troubled if the violence reoccurs; hence the Act enforcement is essential.
It should depend on the government's evaluation on news concerning the anti-government people's movement, Chuan said.
"Actually, some people do not care how the country will be damaged so they want the damage to occur," Chuan said.
The red-shirted people's core leaders, who canceled the rally planned on Aug. 30, have announced they might hold a mass rally on Sept. 5, 12, or 19, to demand the coalition government to dissolve the House.
But, the rally won't be beyond Sept. 19, they said, while the 19th of this month will mark the third anniversary of 2006 military coup that ousted ex-premier Thaksin Shinawatra, who has been perceived as the real leader of red shirts.
