Software and hardware are fundamentally different so it&#x27;s hard to find a close analogy, but if Apple creates this tool (that can be applied to any phone (or at least a large subset of their phones)), it&#x27;s essentially the same as if the decryption tool were present in every phone, even ones sold before the commission of a crime.<p>The closest parallel I can think of is the Gun Microstamping law (which would require that bullet casings be stamped with a mark identifying the gun it was shot with). This has (as you might expect) generated a lot of controversy and lawsuits.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Microstamping" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Microstamping</a>
