✓ Balanced Reporting [9/10]: The headline accurately reflects the content by identifying the key event (shooting at Mexican pyramids), the location, and the perspective (a B.C. tourist). It avoids exaggeration and focuses on a firsthand account.

"B.C. tourist recounts moments before shooting at Mexico pyramids"

✕ Framing by Emphasis [6/10]: The lead emphasizes the mundane nature of the tourist photo just before the violence, creating narrative tension. While effective, it slightly dramatizes the moment through contrast.

"It looks like a typical tourist photo, as British Columbia woman Barbara Welsh and her friends smile near the foot of the famous Pyramid of the Moon..."

✕ Appeal to Emotion [7/10]: The use of vivid survivor quotes like 'waterfall of people just rolling down' evokes strong imagery and emotion, potentially influencing reader perception more than informing dispassionately.

"And then I looked up and it was like a waterfall of people just rolling down the Pyramid of the Moon."

✕ Loaded Language [6/10]: The phrase 'played strange music, ranted about hating tourists' uses subjective descriptors ('strange', 'hating') that frame the shooter’s behavior judgmentally without clinical or official context.

"played strange music, ranted about hating tourists"

✓ Proper Attribution [9/10]: Most claims are attributed to officials or the survivor, maintaining objectivity. Descriptions of the shooter’s actions are tied to official statements.

"Officials have said they are working to understand the motive of the shooter, who reportedly planned the attack..."

✓ Proper Attribution [10/10]: Key details such as the attacker's identity, actions, and weapons are directly attributed to the attorney-general of the state of Mexico, ensuring accountability.

"said Jose Luis Cervantes Martinez, the attorney-general of the state of Mexico, which includes Teotihuacan."

✓ Comprehensive Sourcing [9/10]: The article includes a survivor, official government sources (Mexican Security Cabinet, state attorney-general), and identifies victims by nationality, offering a multi-perspective account.

"The Security Cabinet of Mexico identified the one Canadian taken to hospital as 29-year-old Delicia Li de Yong."

✕ Omission [9/10]: The article omits key context from other reporting: the gunman’s prior visits to the site, the verified social media video with threats, and the fact that the ammunition was restricted to military/police use—details critical to understanding premeditation and security failure.

✕ Cherry-Picking [8/10]: While mentioning the attacker’s motive is under investigation, it omits the attorney general’s statement about a 'psychopathic profile' and imitation of past violent events, which provides psychological context.

✕ Selective Coverage [7/10]: Focuses on the Canadian victim and survivor, appropriate for a Canadian outlet, but downplays broader implications like security response or international concern, which other outlets highlight.

"Officials have confirmed a Canadian woman was killed and at least 13 other visitors were hurt in the attack."
