EDIT: I believe you are misunderstanding the meaning of my previous comment based on its use of indefinite pronouns and how it was physically structured relative to the quote block. Rather than rehash it here, please re-read it.[1]

EDIT 2: Looks like my Edit window timed out. I meant to also update this line as follows:

    Neither the original DallasNews article nor the TechCrunch article
    makes any such assertion about the officer's use of his surname.

I'm not going to call him a liar, because that presumes malice. He was wrong and irresponsible in his defaming statement.

EDIT 3: One last time for clarity, the kid felt his name to be relevant (which still does not mean his name was in fact relevant), but did not assert that the "police made repeated mention of his surname", which, apart from the mischaracterizations, was specifically what I was refuting.
