New York ? It’s generally not a good idea to pick a New Yorker at random, go through his things and slow his rush to the subway. Nobody needs another irritation on a hot, crowded, smelly commute.

But city straphangers submitted calmly Friday as police inspected their bags and briefcases after the latest attacks on London’s Underground. Some were skeptical, but most said they were glad for the security.

Ron Freeman, 25, a stockbroker whose backpack was searched, said, “They should have done this a long time ago, ever since 9-11.”

The NYPD said there had been no arrests and no seizures of weapons, drugs or other contraband by late afternoon. Some people left rather than submit to searches, however.

Random searches also were being conducted on buses, ferries and trains to the suburbs. Outside a Long Island Rail Road station Thursday night, police charged a man after discovering a Taser, a police-style baton and a pair of chukka sticks in his car, but said he had no terrorist links. The man was arraigned Friday on two counts of possession of a weapon.

On the subways, which are used by 4.5 million people on the average workday, the inspections started Thursday and were expanded Friday.
