Yes, in this case there is a minimal amount of details, but there is enough suggest a likely chain of event of that night.
The only things that we really know that happened that night are:
a) the cyclist fell off of his bike
b) a concerned citizen called 911/the police
c) the cop who according to the article was on the job a month saw him take something from his pocket & put it in his mouth
d) the man on the bicycle did not respond to the officers attempts to pull him over
e) the officer resorted to tasing him
f) the man on the bicycle ended up dying
g) family of the deceased told the newspaper that he was not only hard of hearing but had a history of suffering from seizures
Given the last item it is reasonable to presume that he did not hear either the sirens or the officer yelling out of his window, and that what the officer witnessed the deceased take out of his pocket and put in his mouth was his anti-seizure medicine.
The deceased did NOTHING (from what was reported) to warrant either being tased or losing his life over.
