Questions about subway security inspection. Is it legal to ask for an ID card?

Subway security inspection is legal. The Law on Public Traffic Management clearly stipulates that,

Controlled knives refer to daggers, triangular knives, spring knives (jumping knives) and similar single-edged, double-edged and triangular sharp knives.

Controlled tools include the following:

(1) Dagger, triangular knife, triangular scraper, semicircular scraper, invading knife, peeling knife, sheep bone knife, hunting knife and spring knife;

(2) Single-edged and double-edged sharp knives with self-locking devices or non-foldable knife bodies with a height of more than 8 cm;

(3) Martial arts knives (capable of edging), swords and other instruments;

(4) Tibetan knives, waist knives and boot knives used by ethnic minorities;

(five) other knives that may endanger public order.

Identification standard of controlled tools

Anyone who meets one of the following criteria can be identified as a controlled tool:

Dagger: a single-edged, double-edged or multi-edged sharp knife with a handle, a knife rack and a blood groove, and a tip angle of less than 60 degrees; Triangular scraper: a processing tool with three blades; Spring knife with self-locking device: after the knife body is unfolded, it can be fixed by spring or bolt and self-locked; Other similar single-edged, double-edged and triple-edged sharp knives: all kinds of single-edged, double-edged and multi-edged knives with the tip angle less than 60 degrees and the blade length exceeding 150 mm; Other single-edged, double-edged and multi-edged tools with a top angle greater than 60 degrees and a blade length exceeding 220 mm.

All kinds of martial arts, crafts, gifts and other knives with uncut blades and chamfering radius greater than 2.5 mm are not controlled knives.

It is very dangerous to carry controlled knives in public places, otherwise many people will be injured or even killed. No matter what kind of knives, subway trains and other crowded places are strictly carrying knives and guns. If there is no limit, then think about it. Anyone who defends himself with a knife, if young people are more impulsive, there will be casualties, and how many more people die every year in the country.

It is neither illegal nor legal for the community to require real-name registration of ID cards.

The community belongs to private houses and some people's public places. Ordinary people have no right to go in unless you live in a community. But how to judge whether you live in it and completely restrict outsiders' entry will also bring disadvantages to the owners. Therefore, in order to ensure the safety of people in the community, most residential properties will require you to provide ID card registration, otherwise you will not be allowed to enter to reduce risks.
