If Wired stopped getting these experts on, it would be a crime.

He looks like he would be everybody's favorite middle school teacher

“How many people got away with murder before forensic science improves and DNA?”

1:55 : “a better question would be how many people got wrongfully convicted before forensic science”

YES

I actually had the pleasure of working with Matt in the field, and he is a truly an expert on the subject matter and a genuine person.

[ashleymurphy]

You can tell he testifies often by how simply he explains things. In forensics myself (drug analysis) and this was great!

[Sarlat]

I wish someone asked a question regarding the mental toll of encountering some really gruesome and heartbreaking crime scenes on a regular basis. I appreciate what people in forensics do, but it would be my nightmare job for that reason. Curious on how they deal with it.

On the unique fingerprint. It does happen that people are close enough to get false positives. In the Spain bombing case, there was a positive fingerprint match on someone in the states who had never been to Spain. If I recall correctly, it was determined they weren't exactly identical, but they were so close that the automated detection had picked them up

As a former computer forensic specialist this was excellent!

That magnifying glass analogy was a great example of “baffle them with bull 💩”

[khalilahd.]

I love these expert interviews! I never know what I’m going to learn about but I’m never disappointed 😅❤

Expectation: How to get away with murder?
Reality: Here's how we fold a paper into an envelope.

[myragroenewegen]

You have to respect how this guy brings of the fallibility of forensic evidence and wrongful conviction of his own accord. He is careful not even to presume guilt for OJ Simpson. This is the forensic expert we want in the court room.

[spdvr]

as someone who wants to specialize in forensics, this is a video i’ve been dying to see and very happy it’s finally happened.

[CoriCoid]

Get a forensic anthropologist on here!! They handle the identification of skeletonized remains (when the body doesn't have a face to ID them by) and finger prints

[momanmirul]

One more question, how do investigators decide to just go back to an old unsolved case and restart the investigation on it? Do they have free time on a random day and just say "Oh, let's try out this new tech on this one cold murder case back in 1963"

[jayshap.]

Seriously, these series are the reason why I'm still on the internet

[justayoutuber]

I would like to see him break down movie / TV scenes on what is accurate or incorrect.

[ecvjtv]

I wanna see this guy and Victor the mortician to do one together! :D

[sabrinashelton]

I need to know more about the "stepfather burying the body in the backyard" case.

[mckenziewoyak]

i actually remember learning about body farms a while back and how if you donate your body to science in may end up at one and it was so morbidly fascinating

[taryncole]

The examining and testing of how bodies decompose that he's talking about are called body farms. They are super cool and fun to learn about
