Do modern Jewish cemeteries separate the "righteous" from the "wicked"? I have read in various sources that "we don't bury rashim near tzadikim"--that people must be buried near others of similar righteousness. From this page:
"The halachah states that one should not bury an evil person near a tzaddik, nor even a very wicked person near a mildly wicked person, nor a good person near an outstandingly pious individual (Sanhedrin 47a; Rashi, ibid.; Shulchan Aruch, Yoreh Deah 362:5)., [...] The Gemara explains that there were therefore different cemeteries even for different levels of rishut, evil. For example, there were different burial areas for those killed by beit din via stoning and those killed by sword.
"[...] Those of similar religious and moral stature should be buried next to each other. If, however, a tzaddik and a rasha are buried next to each other, it may not be necessary to move the rasha, although some separation, such as a halachic partition, is usually advised (see Gilyon Maharsha, Yoreh Deah 362:5; Shu”t Chatam Sofer, Yoreh Deah 341; Minchat Yitzchak 6:136; Shevet HaLevi 7:193). [...] Rabbi Shmuel Engel (Shu”t Maharash, 3:65) permitted one to move his wife’s grave when it was discovered that she was mistakenly buried in a section of the cemetery reserved for Shabbat desecraters. [...] Thus, only in a Jewish cemetery does one find separate burial sections for societies of like-minded individuals."
Are these distinctions imposed in today's Jewish cemeteries, and to what extent? For example:
Are there still separate sections for those guilty of different violations, such as Shabbat desecrators and suicides?
Are "burial societies" based on level of religious observance and righteousness actually common practice?
Is care still taken to ensure that a tzaddik is not buried next to a rasha, and would the graves of a tzaddik and a rasha be separated by a halachic partition even today?
