Can the police directly kill a drug dealer when they catch him?

If you shoot directly, it is equivalent to delegating jurisdiction to the police. This may be feasible in practice, but it is never certain in theory.

Because once it becomes law, it theoretically gives the police the right to kill people according to their own judgment. Degang Guo had a cross talk joke that he mistook a jar of ashes for drugs. If the police have the authorization to directly kill the drug dealer, they can directly kill the old lady, and the joke will become a tragedy.

In this case, the police actually need a procedure to judge someone as a drug dealer, but procedural justice requires the judged person to participate in this process, which is equivalent to raising the threshold for the police to handle cases.

The modern system is basically based on the restriction of public power. In fact, the police will even restrict the right to arrest inactive criminals, and an institution is needed to approve the arrest warrant, let alone kill them directly.
