Estonian law obliges telecommunications companies to collect data on phone calls.
Justice Minister Liisa Pakosta wants to end data collection. She wants to change Estonian law.
Interior Minister Igor Taro disagrees with Pakosta's plan. Taro says that communication data is important in investigating crimes.
Taro wrote that Pakosta's plan will not help the police. Serious crimes cannot be investigated without communication data.
The Ministry of the Interior wants the government to be able to store data for three years. They also want to store data near the border.
Taro says that communication data is necessary for security.
