On the one hand, as a result of technological development nowadays, phones have become a real weapon, not only a way of communication. Many countries, especially unstable ones, need to track mobile phone activity to avoid terrorism and dangerous crimes. Terrorists and criminals usually use their mobile phones to share crucial information as well as to plan their crimes, which is, without a doubt, a huge danger. Therefore, by tracking and monitoring their calls, governments can prevent serious crimes, despite the ethical concerns. Taking the example of the terrorist attack that took place in Tunisia in 2018, if the government had not obtained information and details by tracking the messages, the result could have been even more serious. That’s why access to personal information can sometimes bring important benefits for the country.
