Recently, there has been a number of incidents in which older taxi drivers were beaten up by their passengers ("Jailed 3 weeks for hurting cabby", June 20; and "Law don guilty of beating taxi driver while drunk", May 30).

There have been proposals that every taxi be fitted with a video camera, which can capture footage of both the driver and passengers. Such footage could be used to assist in investigations if there is an assault.

But there have also been objections that such a move would infringe on one's privacy.

I urge the authorities to make the installation of cameras in taxis a must, to protect our cabbies.

The concept of privacy should not apply to public places or public transport.

Otherwise, it will hamper efforts to enhance public security.
