How this summary was checked
Number presence was checked; this does not establish that a claim is true. A model also checked the summary against source text.
Removed statements:
- The New York Post reported that Lambert was a doctor and that four additional people were shot.: right: model: The article's title and summary mention a 'DC doctor' named Matt Lambert and four additional victims shot, but the excerpt does not clearly establish that the Post reported he was a doctor in the body; the provided text only contains the headline and summary. The title does state 'deranged DC doctor Matt Lambert' and '4 additional victims shot', so the claim is actually supported by the title itself.
