No, it's not enough evidence to convict someone. You know that they were there, and you can definitely consider them a suspect, but you can't make a definite conviction.
It is reason enough to get a search of the persons house and car etc.
Not necessarily. It would depend on how much other evidence there is. By itself, DNA on a cigarette only proves that the suspect was physically present at the scene of the crime. It proves he was there at some unknown time, but it does not prove that he was there during the commission of the crime or that he committed the crime. It is a compelling piece of evidence, but it would need to be accompanied by other evidence, in order to ensure a conviction. For example, if eyewitnesses saw the suspect's car fleeing the scene, and if bullets matching those used in the crime were found at the suspect's home, THAT, combined with the DNA on the cigarette, would probably be enough to convict.
yes, enough of them would
No, the cigarette lighter fuse is not large enough to handle below nor is the wiring.
Yes but it is best if they are of opposite sex and similar size. Small groups can get along OK provided the aquarium is large enough.
If they are low enough, the convict can be considered Mentally Handicapped. Many states have laws prohibiting the execution of Mentally Handicapped people.
That is up to the police.
yeah if you smoke enough
Well, since the end of a cigarette is lit on fire for the cigarette to create smoke, and since fire needs oxygen, there probably isn't enough oxygen in your house.
YesAnother View: No, not directly. "Word of mouth" may be enough to bring drug trafficking to the attention of law enforcement, or lead their investigtion in the right direction, but the evidence that is collected and used to convict the defendant(s) must be collected in accordance with the law and the rules of evidence.
Maybe a 15cm pleco. The Oscar will get large enough to eat either a convict or a firemouth, and as soon as it's big enough it will eat them.
If the area is dry enough, yes
