so - the police should use arrest and imprisonment without bail - as a means of investigation? you're joking I hope.
so, since they always suspect family members as the main suspects in these cases - they are going be arresting alot of husbands/wives/fathers/mothers in this country.
Like I said, I don't condone it. They happened to get it right this time (everybody in Nashville "knew" this guy did it - you would have had to be here the last 10 years), and when they arrested him, we all assumed they had the goods on him.
What they had was: love letters from him to another woman that were hidden away by his wife (at her art studio), an appointment with a divorce lawyer the day after she disappeared, a computer hard drive that disappeared between the first search (when he wasn't a suspect) and the second (when he was), her car found at an appartment complex with all of her stuff in it, and fibers that matched the husband, and testimony from some Mexicans that he had said he killed his wife.
IMHO it wasn't enough to prove beyond a reasonable doubt that 1) she was even dead and 2) he killed her. But even without his jailhouse behavior, the above was enough to convince me that he did it (and most of Nashville, too). But there's a difference between "knowing" he did it, and "proving" it.
Like I said, in this case, the state got lucky. There was nothing heinous about arresting him and trying him with what they had (it was enough to at least try),I just don't think they would have convicted him. Sometimes, you just get lucky.
