Amnesty International has questioned whether proposals to give all frontline police officers Tasers is an effective way to deal with the current terror threat.
Commenting on the proposals the charity's arms programme director Oliver Sprague said he believed the defensive weapon "can have a part to play in policing operations" but that they "should be used sparingly and only by highly-trained officers."
He added: "We'd ask the question: where's the evidence that a terrorist will be deterred by the knowledge that police officers have Tasers at their disposal?
"And who on earth thinks that if there's a real instance of terrorist activity that Tasers would ever actually be sufficient for our law-enforcement officers?"
The Met Office said sleet and snow showers would affect parts of Scotland and Northern Ireland today, with snow falling to lower levels and extending further south through the day.

The death of an Islamic State chemical weapons expert is expected to temporarily "degrade and disrupt" their use against "innocent people" US Central Command said in a statement.
US Central Command has issued a statement saying Islamic State chemical weapons expert Abu Malik, was killed in a coalition airstrike on January 24 near Mosul, Iraq.

When he joined Islamic State, also known as ISIL, it gave the insurgent force a chemical weapons capability, the statement said.
Tough new laws announced by Canada will make it a crime to call for a terror attack and allow police to detain anyone suspected of being involved in a plot without charge for up to seven days.
Work to toughen the law began in October after a gunman killed a soldier at Canada's national war memorial in Ottawa before storming parliament.
The attack came two days after a man said to be inspired by the Islamic State (IS) group, ran over two soldiers in a car park in Quebec, killing one and injuring the other before being shot dead.
Under the current law it is a crime to make a specific threat, but the new measures will criminalise calling for general terror attacks on Canada or to promote or advocate others to carry out terrorism elsewhere.
The penalty will carry a maximum of five years in prison and authorities will also be able to remove terror-related material from any Canadian website.
Mr Harper said jihadists had declared war on Canada and it would be a grave mistake to ignore their threats.
