For  centuries  people  have  created  the  rules  of  morality,  which  have  been  changed  during  the  history  of human  beings  modified  and  adjusted  to  contemporary  societies,  putting  the  bricks  of  civilization  one  on  another.  Unfortunately,   the  more  complicated  civilization  becomes  the  more  extreme  the  violence  becomes.  A  disturbing  percentage  of  American   children   perform  serious  criminal  offenses   and  are  becoming  a  threat  to  the  society.  Juveniles  are  getting  involved  in  the  criminal  world  more  and  more,  consequently  forcing   the  government  to  take  measures  to   now  deal  with   higher  rates  of  juvenile  crime.    Proposition  21  is  especially  effective  with  gang-related  criminals,  because  gives  the  state  the  ability  to  try  children  as  young  as  fourteen  years  of  age  as  adults.  If  I  had  the  opportunity  to  vote  I  would  be  for  Proposition  21.  Even  though  teenagers"  brain  is  not  ready  for  this  law,  more  and  more  violent  crimes  are  committed  by  teenagers,  which  proves  that  the  law  before  Proposition  21  didn't  have  the  potential  to  prevent  this  progress,  while  the  current  law  has  both  the  rehabilitating  component  and  the  deterrent  factor  leading  to  a  fair  justice  system.    .
            
	The  development  of  the  human  brain  is  a  dreadful  factor  in the  issue  of  the  punishment  of  juvenile  crime.  An  opponent  of  Proposition  21,  Kate  Fogle,  in her  article  named  "Choosing  Which  Story  To  Tell"  argues  that  the  brain  of  a  child  under  18  is  not  fully  developed   and  that  "Setting  the legal  majority  at  18  reflects  the  actual  capacities  of  young  people  rather  well"  (Fogle  1).  Also,  the results  of  a  research,  shown  in  the  article  " Foundation  criticizes  trend  of  trying  kids  in  adult  court"  written  by  Jonathan  D.
