When the police receive the riot alarm, can they find out its correct location according to the short message?

No way! If the police want to locate according to the mobile phone, they must first file a case with the criminal police and then apply for it by the police. After the approval of the police force, sub-bureau and municipal bureau leaders, the technical department of the municipal bureau can carry out it. The formalities are cumbersome, and we have to wait until tomorrow night at the earliest. It will take several working days for the technical department of the city bureau to trace it. Secondly, general harassment does not meet the filing standards. Because it is impossible to file a case, it is feasible in theory and impossible in practice.
