800 people were beaten or kicked to death in the U.S. in 2010. Over 700 for 2011. So we are to believe that a football player could not kill a woman with his brute strength?
Motive is the most important thing. We need to examine why Alpha males in failed relationships kill their partners then themselves.
I will repeat this wherever whenever I think it is appropriate: Criminologist Marvin Wolfgang hated guns. He stated if he were Mustapha Mond, dictator of the world in Huxley's "Brave New World" he would ban all guns from the civilian population and most of the police.
He also studied hundreds of real murder cases.
"More than the availability of a shooting weapon is involved in homicide. Pistols and revolvers are not difficult to purchase (on the street) ... The type of weapon used appears to be, in part, the culmination of assault intentions or events and is only superficially related to causality. To measure quantitatively the effect of the presence of firearms on the homicide rate would require knowing the number and type of homicides that would not have occurred had not the offender_ or, in some cases, the victim_ possessed a gun. Research would require determination of the number of shootings that would have been stabbings, beatings, or some other method of inflicting death had no gun been available. It is the contention of this observer that few homicides due to shootings could be avoided merely if a firearm were not immediately present, and that the offender would select some other weapon to achieve the same destructive goal. Probably only in those cases where a felon kills a police officer, or vice versa, would homicide be avoided in the absence of a firearm." M. WOLFGANG, PATTERNS IN CRIMINAL HOMICIDE 82-83 (1958). (my emphasis added)
Details. Wolfgang studied the homicide files of the Philadelphia Police Homicide Squad, 588 criminal himicides (588 victims, 621 offenders, years 1948-1952) and his study was published 1958 (U PA, Oxford U and John Wiley). During part of the study Wolfgang rode with the homicide squad; he was sitting in the homicide squad one night and a murderer walked in and surrendered to him and confessed. Of 550 known victim-offender relationships 65% were close friend, family member, lover, homosexual partner, etc.
Side issue: "Pistols and revolvers are not difficult to purchase (on the street)" and that was 1950s Philadelphia. My experience has been that casual or criminal sales of guns (often stolen) were common among hoods in my neighborhood in the 1950s and 1960s. If anything, the federal gun laws starting with the 1968 Gun Control Act have strengthened the black market while making hoops for the lawabiding to jump through.
