The Issue: A mentally ill ex-NYPD cop and current NYC educator allegedly stabbing a Brooklyn jogger.

Once again, a beautiful and good person is apparently murdered by a mentally unstable person (“Killer’s deranged excuse,” Nov. 9).

The NYPD and the Marines ultimately rejected him due to mental illness, yet the city Department of Education didn’t notice the obvious signs, such as talking to himself? Even the 12-year-olds knew he was a danger.

My heart breaks for the family and friends of Katie Suarez. Why her? Was she someone he stalked? She was only a few yards from the bank she worked at. How far from the scene did Sayed Mohassib live?

All of this will come out eventually. But in this young lady’s memory, we must do a better job vetting people — especially when the job deals with children.

And, if you ever believe you’re a victim of stalking, don’t brush it off; make people aware and do not go out alone.

The level of incompetence that led to Katie Suarez’s murder is mind-boggling.

How do you explain this lunatic passing the psychological test to be accepted into the NYPD the first time? He left it to join the Marines and was almost immediately discharged, deemed psychologically unfit to serve.

The final and most disturbing bit of incompetence is this psychopath then being hired by the Department of Education.

Tragically, Suarez became an alleged victim of this ticking time bomb, but her murder resulted in him finally being taken off the street, something a clearly inept system was unable to do.

The man accused of killing the jogger on the Belt Parkway said he blacked out and found blood all over himself after getting home.

What’s more disturbing is that the NYPD found blood on the walls of his bedroom in the apartment where he lived with his mother. How did she not see this?

These days, there are too many stories similar to the violent death of Katie Suarez. The problem is there is not enough vetting of who the government is letting into the Police Department and education system.

Instead, they continue to prioritize diversity, equality and inclusion.

The Issue: A protest targeting Jewish-owned Phila­delphia businesses before the Kristallnacht anniversary.

Kudos to the overwhelming crowd who jeered antisemitic Philly bike riders attempting to intimidate Jewish business owners (“Boycotting hate,” Nov. 9).

The “City of Brotherly Love” would be far better off if the haters would just ride out of town and never return.

I am not Jewish, only a simple New Yorker, but I can see a copycat protest against Jewish businesses in New York City happening, given Mayor Mamdani’s record of anti-Jewish behavior.

I hope the midterm results were not a dog whistle for even more anti-Jew actions. If so, all good New Yorkers must be ready to stand up.

The Philadelphia group of Jew-hating sociopaths called Philly Bike on Your Left are a direct result of the antisemitism spewed by every member of the DSA.

Like Joseph Goebbels, people like this spew the big lie about evil Jews from the 3,500-year-old homeland of Israel controlling the world.
