Just a correction to one of your reader's letters. Jennifer Chin wrote in 'DAP, PAS should sort things out amicably' that in the United States, there are states which enforce a law that requires purchasers of alcohol to prove that they are 18 years old or above.

Actually, federal law imposes a minimum age of 21 for the purchase and consumption of alcohol, in all states within the US. Although all states have autonomous powers to impose a lower age limit, 18 for example, all states abide by the federal requirement.

As far as gambling is concerned, she is right. There are regulations on such activities. In the US, for instance, gambling is only legal in the state of Nevada (where Las Vegas is located) and in the city of Shreveport in Louisana.
