Okay, so maybe that’s not exactly the defense employed, but it’s damn close. As reported in The South Asian Post:
An Indian man escaped a possible death sentence for drug trafficking after his lawyer told a court it was impossible to walk with a stash of heroin in his underpants.Mumbai police alleged Dhirendra Kamdar was carrying two kilograms of the drug in four, 500-gram packets in his underwear when they picked him up as he walked from a guest house to get a taxi to the city’s airport. But when the case came to trial, Kamdar’s lawyer Ayaz Khan said it was impossible for anyone to walk one kilometre with such an amount of drugs concealed in his smalls, the Daily News and Analysis newspaper said.Khan demonstrated his theory to the judge using four identically-sized bags filled with sugar, and was acquitted of the charge on lack of evidence.
500 grams equals about 1.1 pounds. So the total was almost 4.5 pounds. That would definitely alter your gait.
