It was the first result when I searched for it. The original source is this:
https://www.tehrantimes.com/news/491344/American-youth-break...
Points for it being legitimate:
- Congruent with what the ADL publish on their own website
- recording sounds fine
- ADL have not denied it
Points for it not being legitimate
- Heavy biased source
- I'm not an audio engineer, so I only have an amateurs intuition of what sort of recordings sound real
Why are you using justicereport.news as a source? I hadn't heard of it but after clicking through it a little it's clearly a fringe crazy spam site (objectively-- take a look at some of the articles)
If this is worth discussing you can easily find a better source
