[Star Wars] "These tracks are side by side. Sandpeople always ride single file". But why do the Stormtroopers bother attempting the deception?

In *Star Wars: A New Hope*, Stormtroopers searching for R2D2 attack the Jawans, and make it look like an attack by Sand People. Nonetheless, Obi Wan easily sees through their deception. Why do they bother doing it in the first place?

* Scattering sticks and making fake Banta tracks is a waste of time in what's meant to be a search they have to complete quickly.
* The deception is obvious at first glance to Kenobi. If it's a legal question, then presumably it wouldn't stand up to forensic scrutiny.
* This comes just after news that the Emperor has dissolved the Senate and given autonomy to the regional governors, so it's not like there are any political considerations.
* They're Stormtroopers equipped with weapons: the people they were searching for couldn't have stopped them anyway.

So, what was the point of faking an attack by Sand People at all?

The deception was obvious to Obi-Wan. It would not have been obvious to anyone else. For one thing, Obi-Wan was a highly experienced and very intelligent Jedi Master, which nobody would have expected to be in the area. For another thing, Obi-Wan had lived in the Jundland Wastes for nearly 20 years. Over that time, it would have been absolutely necessary to learn how the Sand People move and act. Nobody else traveled the Wastes often or long enough to need to learn that much about Sand People, which were widely considered to be savages and the only good one was a dead one.
