One reason Texas convicts so many innocent people is our lax standards for allowing the State to admit “scientific” evidence at trial. Given the State’s nearly limitless resources for experts, supply is racing to catch up with demand, whether or not the science is sound or not.
Trial courts are supposed to be the gatekeepers of scientific evidence and limit what the jury can hear. That sounds great in theory, but in practice the State almost always gets in whatever “expert” they designate. It was this atmosphere that allowed the complete bullshit “science” of “dog scent lineups” to pollute our courtrooms.
The latest victim of junk science is Michael Arena. Michael was wrongfully convicted (his “victim” has completely recanted, stating that she was coerced by her mother to lie) of sexual assault, and sentenced to 20 years.
