An error proves that there are errors here. And you won't prove a lot when any- and every-thing should be considered as a probable error.
And the breach of the rights isn't an error. For example.
Actually there are a lot of conveniences the courts allow.
Your accounts on Internet are usually used by you. Indeed. But bigger the crime, bigger the profit and the danger - more are the chances that the actual criminal used hacked account. The courts won't see it this way.
Most of your fingerprint are left by you. Indeed. But it takes just a couple of minutes to move 'em from your garbage to some weapon. Any criminal may do it..
Most of your hairs are left in the places where you were. But. Even when they weren't displaced by purpose there are a lot of ways of transfer. Wind, cats and dogs (from the same garbage), birds and do on.
And the fact of your presence in the area. They almost never demand to evaluate how many people were in the area. It's ridiculous...
And than, that ruling of the Supreme Court from the 2013. If you don't invoke the Fifth Amendment before the arrest you have no rights and your silence would be used against you...
