Oral polio vaccine (OPV) contains an attenuated (weakened) vaccine-virus, activating an immune response in the body. When a child is immunized with OPV, the weakened vaccine-virus replicates in the intestine for a limited period, thereby developing immunity by building up antibodies. During this time, the vaccine-virus is also excreted. In areas of inadequate sanitation, this excreted vaccine-virus can spread in the immediate community (and this can offer protection to other children through ‘passive’ immunization), before eventually dying out.
On rare occasions, if a population is seriously under-immunized, an excreted vaccine-virus can continue to circulate for an extended period of time. The longer it is allowed to survive, the more genetic changes it undergoes. In very rare instances, the vaccine-virus can genetically change into a form that can paralyse – this is what is known as a circulating vaccine-derived poliovirus (cVDPV)."

The US on the other hand is a different story. In 2005 one man was convicted to 20 years imprisonment for hentai. In 2016 a man was convicted to 10 years imprisonment for owning a coloring book.

However, ABB created and exported (among others) the BWR90+ during the nineties, proving your statement wrong. You can read about it in the newspaper about how it iw popular to study nuclear power again (article from 2010). http://www.dn.se/nyheter/politik/karnkraft-hett-pa-universit...

Upgrades between LTS releases are not enabled by default until the first point release, 14.04.1, scheduled for July. It is recommended that most LTS users wait until then before upgrading to 14.04. You could add a '-d' flag if you're in a hurry!
