He..he..He.. Same same.. I also using the same tactics..

But you are right.. Last week got this Spore Custom Malay abang looking at me in a strange way when I heading back to Spore.. Luckily I acted innocent.. Kinda close shave for me.. Think I will just bring 2 Dunhill packets instead of the usual carton when at JB.. Too risky..
Sometimes you cai also useless. If suay suay that Customs or CISCO chap wants a more thorough check, pengsan. If 100% check, no chance to escape.
5 years ago, my friend kena caught with about 30 cartons. He was in long-sleeved shirt, specky, decent face, Mercs etc. The profile didn't meet that of a smuggler. yet when he drove in to the booth to stamp his passport, he was immediately directed to the 100% check.
As a veteran investigator, I asked him to tell me his MO from beginning to end. Managed to arrive at a sensible conclusion why and how he was caught. Weeks later, a friend of his also kena caught. MO same same.
Many in this trade get the stocks from a particular seller in JB. Over there, bo cheng hu. They will transfer their cartons openly into various parts in their motor vehicles. Some cars are altered for this purpose. Instead of detouring and unloading their goods into another vehicle, they drove from that location staright to Customs.
If PIs were tasked to flush out the smugglers, all they need to do is to sit at the kpt opposite base and record the car numbers of those seen loading the cartons to their vehicles. End of story. Sure kena arrested.
After my friend served time in jail, his kakis changed MO. They would still get their stocks at same place. Thereafter, instead of proceeding straight to Customs, they detoured to another location to unload their goods into another vehicle. True enough, the first car was directed for 100% check when it arrived at the booth. The second vehicle sui sui crossed.
Lost touch with this chap. Not aware what's being done currently.
