Journalists sometimes use historical photographs to illustrate articles about current events.
Evidence
Journalists sometimes use historical photographs to illustrate articles about current events.
But this recycling of old photographs overstates the similarities between past and present, and thereby denies the individual significance of those current events.
Conclusion
Hence, the [recycling of old] photographs in this manner by journalists distorts public understanding of the present by presenting current events as mere repetitions of historical incidents.
Evaluate
The argument assumes that overstating the similarities between past and present distorts public understanding of the present.
It also assumes that denying the individual significance of the current events distorts public understanding of the present.
