The emergence of crack in the spring of 1986 and a flood of lurid and often exaggerated press accounts of inner-city crack use ushered in a period of intense public concern about illegal drugs, and helped reinforce the impression that drug use was primarily a minority problem. Enforcement of the nation's drug laws at the street level focused more and more on poor communities of color. In the mid- to late-1980s, many cities initiated major law enforcement programs to deal with street-level drug dealing. "Operation Pressure Point" in New York was an attempt to rid the predominantly Hispanic Lower East Side of the drug trade. Operation Invincible in Memphis, Operation Clean Sweep in Chicago, Operation Hammer in Los Angeles, and the Red Dog Squad in Atlanta all targeted poor, minority, urban neighborhoods where drug dealing tended to be open and easy to detect.
In the 1980s, with the emergence of the crack market, skin color alone became a major profile component, and, to an increasing extent, black travelers in the nation's airports and found themselves the subjects of frequent interrogations and suspicionless searches by the DEA and the U.S. Customs Service. These law enforcement practices soon spread to train stations and bus terminals, as well.
aircrack-ng is an 802.11a/b/g WEP/WPA cracking program that can recover a40-bit, 104-bit, 256-bit or 512-bit WEP key once enough encrypted packetshave been gathered. Also it can attack WPA1/2 networks with some advancedmethods or simply by brute force.
It implements the standard FMS attack along with some optimizations,thus making the attack much faster compared to other WEP cracking tools.It can also fully use a multiprocessor system to its full power in orderto speed up the cracking process.
The Zodiac coined this name in a series of taunting letters and cards that he mailed to regional newspapers, in which he threatened killing sprees and bombings if they were not printed. Some of the letters included cryptograms, or ciphers, in which the killer claimed that he was collecting his victims as slaves for the afterlife. Of the four ciphers he produced, two remain unsolved, and one was cracked only in 2020. While many theories regarding the identity of the killer have been suggested, the only suspect authorities ever publicly named was Arthur Leigh Allen, a former elementary school teacher and convicted sex offender who died in 1992.
On August 7, 1969, The San Francisco Examiner received a letter with the salutation, "Dear Editor This is the Zodiac speaking." This was the first time the killer had used this name for identification. The letter was a response to Chief Stiltz's request for more details that would prove he had killed Faraday, Jensen and Ferrin. In it, the Zodiac included details about the murders that had not yet been released to the public. He also said that when the police cracked his code "they will have me".
On August 8, 1969, Donald and Bettye Harden of Salinas, California cracked the 408-symbol cryptogram. It contained a misspelled message in which the killer seemed to reference "The Most Dangerous Game". The author also said that he was collecting slaves for his afterlife.[n 4] No name appears in this decoded text. The killer said that he would not give away his identity because it would slow down or stop his slave collection.
After the Lake Tahoe card, the Zodiac remained silent for nearly three years. The Chronicle then received a letter from the Zodiac, postmarked January 29, 1974, praising The Exorcist as "the best saterical comidy [sic] that I have ever seen". The letter included a snippet of verse from The Mikado and an unusual symbol at the bottom that has remained unexplained by researchers. Zodiac concluded the letter with a new score, "Me = 37, SFPD = 0". 2b1af7f3a8
